Seems we can run pretty much everything on a single-phase AC, then why bother with 3 phases??

ElectroBOOM HI
Thought you were giving away one for patreon and one for KZhead.
Nope, he said "...I'll give away one of them to my Patreons... ...as well as you, the viewers..." meaning everyone was in the same pool. If there were more than one being given away, he would have specified how many there were.
plzz give it to me
No! Too late :(((
I hold my breath every time he connects something.
Same here
lmao
same
Haha, or at least prepare mentally so that you don't have to be quite as startled, huh?
Yes
I appreciate how you intentionally mess up and make sparks to show us what not to do.
Cody: Hey! Don't ruin the illusion :(
i almost shit my pants
Cody, you do much the same thing. I told you once that you reminded me of "Mr. Wizard", a Saturday morning b/w TV show of the 50's. He was always coming up with weird experiments that would dazzle us. Thanks to you both....
Hey man long time no see did you ever get your channel straightened out?. Love your vids man!.
:D I don't suppose you can intentionally mess up your experiments, you could lose a finger or two!
I worked at Siemens Electric for 12 years and you explained 3 phase systems better than anyone I worked with, that job was the best job I ever had.
I currently work there!
Did you cringe at 6:44?
That is so sad, 12 years 🤔😅
What was the pay though? Was it good pay or great pay?
I learnt about this 1.5 years back in my 2nd semester of Engineering but I understood it today.
KZhead >> All engineering universities combined
Physics (electricity year 2) , what's 3 phase, lecturer just jumped in like we new everything already and used a lot of math which got me confused more.
@@A_I_N_P My major is Information Science Engineering (basically computer science). In the the first 2 semesters we are taught the basic concepts of different branches like civil, mechanical, electrical etc.
@@A_I_N_P meh it sometimes takes time for concepts to sink in, especially if he's doing his degree in 4 years.
Same lol
I got a degree in electrical and electronic engineering many years ago but the theory wasn't backed up with much practice or demonstration. You've not only demonstrated the concept but injected your wonderful enthusiasm for the subject. Thank you!
I also got a master degree and must admit i didnt get so much Important Background theory, i just calculated what my Professor wanted me to, without understanding what im really doing... Thats why Love this channel
It's because the professors at the universities don't really understand what they are teaching. Those who can do....
@@t07minas so do you work at KFC
Classes did me no good, same. The teaching fails in part because they use the term EMF (electromotive force) for voltage as if it were some sort of mysterious thing, they should be calling it EP, electrical pressure, from electron crowding, electrons aren't comfortable being crammed together, not unlike air molecules in a balloon. It's possible that electrons actually have no charge and instead it's simply this: When a bunch of them are crowded together, we call that negative, and when they have been sucked away, similar to a vacuum, we call that positive charge. The difference between electrons flowing in a wire because there's a crowded area and less crowded area for them to move to versus water or air in a hose trying to move from a pressurized area to one less pressurized ... is the magnetic field electrons cause when they move. That's pretty much all there is to it. But moving water, air or even light might also have a field we just haven't discovered yet. Like you guys are saying, it wasn't until I started working with actual stuff that I got it, one day, bam, it clicked, a eureka moment, and I also felt betrayed by the teachers at the same time. So then I looked up a 7th grade school book on electricity. And as I suspected, if you know, it is written to sound somewhat ok, but if you're trying to learn, you would never get it from what they say. And that might be intentional.
I have three degrees and none in electrical engineering but I"m pretty sure touching a 3 phase circuit will help you to get a afro and a heart murmur if you are lucky and lots of sleep if you aren't.
His knowledge about electricity is soo high, he became immune to it. Lol
He gets high off electricity.
@Xieq-Jimmy- he is immune to death not shock damage
The man has thick rubber shoes for balls
When he gets electrocuted , Electricity apologizes 😂
I remember one farmer who could work on electric fences while they were live. I don’t know how he was able to take it. Another guy contracts to change a famous brand light bulb and had gotten shocked so many times it done something to his nerves and now he can’t hardly feel getting shocked. Good thing his company retired him!
Had this guy been my teacher in electrical engineering , I wouldn't have missed a single lecture.
We would have made make up classes even on weekends bro
Sir I started watching your videos lately. I am a student of engineering and your videos are beyond any measures. Thanks for your hard work sir, you inspire us and keep our interest firm for electronics.

Mehdi's explosive demonstrations are not only extremely entertaining, but also serve as a very tangible warning about common errors. It also makes me really afraid of messing with electricity, unless I know exactly what I'm doing, and I'm still using all possible failsafes and protection I can. Just brilliant!
Damn…I LOVE your presentation! I went to electronics tech school for two years, studied on my own and worked a a tech. I never quite felt at ease with three phase, the why, the how, and we NEVER had any teacher that was so much fun while still being incredibly informative and even with the joking, there is a very high signal to noise ratio in your teaching! Definitely going to check out your other videos! Thanks!

His 11 min video about 3 phase AC made me understand it better than when I took it for 2 months at school.
at school, most of the teacher spend time on calculations
Same, only mine is for the whole semester.
it took me 20 years from the time i first saw 3 phase, to see this video, to actually understand it. and it is clear as day.
Just like sex ed at school. Learnt nothing in 12 weeks but 1 night with the school slut, I was educated :)
I went through a school for electrical engineering, and i found this to be one of the best lessons on the subject i have ever had the honor to consume.
I always wondered why doubling up 120 made 208 and not 240 but this makes perfect sense because when the phases shift 120 degrees the peaks and valleys aren’t directly over each other so you don’t get the full peak and valley of the wavelength that you would get at 180 degrees
You've explained this so much better than they did at my school many years ago. The advantage of not needing the neutral wires for the combined 0 volts is definitely interesting, I wish they had explained it in this way so it might have stuck. I like your visualisation with the coaster, a simple explanation of a potentially complex subject.
In fact, it's a little more complicated. The circuit is closed through a winding that does not currently have an "amplitude" (popularly speaking). However, we have other influences, such as hysteresis in the case of inductive loads. Note the case where the fan motor was rotated directly by the three-phase current from the motor. He winced and spun slowly. The fourth wire (zero) is often used in similar applications that have a "star" connection. Of course, the sum of currents or voltages in this three-phase network diagram is 0, but this does not mean the absolute cancellation of the fourth conductor. Very high voltage pylons have this conductor at the very top ...
Little tip&trick. We use the paper masking tape (used for painting rooms) and apply it on the printerboard. After printing it can be pulled off a lot easier and the tape discarded.
thanks man
Claudy ? Toi, ici ?
Also letting the part to cool helps to pop it off. Sometimes popping it in the freezer can pop it off. Just let any glass plates cool to room temperature before throwing them in the freezer. Unless you want to buy a new printbed
A truly excellent explanation. I wish this kind of thing was available 30 years ago when I was lecturing this stuff. To be honest, it is even clearer in my mind now. Well done.
this has become one of my favorite channels on YT. Very informative but at the same time super funny and keeps me guessing each time a connection is made or wires touch
08:17 small correction. Three sets of electromagnets placed Mechanically out of phase by 120deg. Very informative and beautifully explained. Can't imagine how much effort you put into making these wonderful material. Thanks a ton. Lots of love🙏
Good point
Agreed
This is the 1st video of your's that I've seen, and I can't believe I haven't heard of you before. Very good content, and I think you have a very likable personality. Very funny, and very fun to watch! Thank you!

I came here from a compilation of abruptly cut screams. I couldn't find the other original clips but this guy's clip had the channel name and I found him. I can't believe I was so lucky.
In Germany all houses have a 3 phase power supply. It is splitted in 3 single phases, but if you are any enthusiast and have for example a CNC machine or car lift in the garage, you can use all 3 phases by making a 3 phase outlet.
Vorteil von unseren Installationen :)
That's freaking awesome.
We have that too at my parent's house. And I think our solar panels output three phased power, not sure about that...
That's genius, things like that are what make Germany awesome, aside from the food.
cokefridger it's a shame houses are only wired for single phase in the states. Probably too expensive for contractors and the power companies to implement
No joke, I'm using this video to learn about 3 phase AC currents before my college starts. I've known about Electroboom before college but now, I'm totally hooked! Thank you so much for the videos Mehdi!

Same here, I finished college last year and have worked in a power plant ever since, my colleagues are good at explaining things but the way electroBOOM explains and demonstrates also helps alot with understanding what is going on in the machinery at work.
7:16. Noises made by the driver ... That’s AMAZING!
Great video, a couple of points. 1 The input power of 3 phase motor with a current of I amp per phase and a phase to is is not 3VI but (sqr rt 3) VI 2 The reason why the motor generator set had a low efficiency was because the magnetic field was just the residual field in the laminations. Full size generator either have a rotating rectifier or slip ring to supply a dc current to the rotor.
Just to know - in Europe you have 3 phases at home not only in industrial areas and the voltage is higher - 230V one phase and 400V 3-phase. The higher voltage got a benefit if you have a fixed power-requirement. You need with 115V a wire with the double width because of the line loss the copper wire has. One interesting history fact about transmission lines - 1882 the first transmission line was built with 2 kV DC over 57km. The efficiency was 25%. And in 1891 the first transmission line with 10kV AC over 176km was built. The efficiency was 75%. Today we use in Europe depending on the distance and economy AC transmission lines between 110kV and 1000kV. The most common used are 3 phase 400kV. Because of the weight transmission lines are out of aluminium. In comparison the weight is 55% of a comparable copper-wire with the same AC resistance and line loss.
im in the states... i always thought if i doubled the voltage to everything in my house ut would lower the load and my electric bill!!!!!
@@sdrake74 If you doubled the voltage to everything in your house you would get higher electric bill
@@Nobody-eg4bi And an even higher bill from the fire department.
@@petehiggins33I understand all these things but what is more important is the wattage so you can use higher voltage but you should in that case give a lot less current (amperage), the most important thing that you should never change the wattage
I also have 3 phase connection but noticed not all homes have

Again, golden material. well explained. I was aware of a 3-phase motor. Your explanation was better, i wasn't aware the degree of phase impacted the voltage. Thank you for this!!
2:36 Ah yes comrade, Distribute equally and balanced
Rayman34128 But that’s not the Soviet Union national anthem, that is the Russian national anthem.
This load belongs to the workers.
I've been a master electrician for 40 years and this is one of my favorite subjects to explain to laymen. 3 phase solves the problem of zero voltage potential and no work being done that occurs twice every cycle of single phase, with 3 phase there is always work being done because the phases overlap by 120 degrees, thereby massively increasing efficiency. Many years ago there also was 2 phase systems where there were 4 current carrying conductors arranged in 2 sets of two that had to be paired properly, it proved to be more expensive than 3 phase, wasn't as efficient and it was a pain in the posterior so it never caught on. We had an old factory in our city that had ancient machines that ran off of a 3 phase to 2 phase motor/generator converter, I hated working on them but just my luck, I was the only person they could find that understood how the electrical parts worked. The only reason they kept them going was because they were specialized machines that couldn't be replaced.
Can you write my IP exam for me??
@@knowledgegod2635 Love to but I'm a master electrician not an IP expert.
@@MichaelClark-uw7ex we don't have master electricians in canada. only apprentice, journeyman and foreman. Love the work but hate the schooling.
Hey wait a minute... Maybe we should use DC!
@@knowledgegod2635 uhhh yes we do
I am a retied electrician and at one time I was lead electrician/engineer for the third highest building in Washington state. With few exceptions, almost every heavy electrical load ran on 3-phase power. We used many VFD's in our air-conditioning plants. I really liked you lecture on 3-phase power and how it works. I have been out of the electrical field for years but your videos are a refreshing reminder of my happy days as a practicing electrician!
In my school we learned about 3 phases current , sometimes paper and pencil can't do that much to make you understand how it works in detail, now I know how it works :) Love and respect for you🙏
LOL@mishaps. But another reason 3-phase systems got expanded a great deal in the early 1900s is because there was an efficient way to rectify the 3-phase current back to DC: the mercury cathode rectifier. These don't work too well with 1-phase AC (the arc gets extinguished on the reverse half of the cycle and is hard to reignite, whereas in a 3-phase rectifier the arc never extinguishes). Remember, there were no high-power silicon diodes back then.
Glass ignitrons like this kzhead.info/sun/q5FpkpGviKB6ipE/bejne.html look pretty nice. (But looking at them will fry your eyes)
Finally a new video! You are the only channel whose videos worth likes before even watching them, because you know good content is coming.

First one to say three phase needs 3 FULL BRIDGE RECTIFIER.
There is a special full bridge rectifier design for 3-phase systems. The pulses on them are much nicer
you need only 6 diodes and a lot less caps for three phase. the output voltage is also higher.

Very interesting video, I am an electrician on a USCG cutter, we use a wye configuration like all ships. Funny story: in trouble shooting a generator we took current and voltage readings on the governor actuator control circuit... I did exactly what you did at 3:05 thinking my meter was set for voltage and killed the governor thus killing the generator and the entire ship's power... That's one way to learn a lesson about checking your meter XD

I did the same but not with main power outlet...it was close...
when i was 14 we had a problem in the house and i tried to measure current in parallel on the main house switch, it was scary as hell. I knew how to do it properly but i was so fed up that i just forgot

Brah! Much love your videos gice great information and SAFETY tips. Always enjoy them.i got a lot of my friends into watching and my kids dig them
In Germany we get all 3 phases at every house. So we can power devices which needs 400V. It is pretty neat.
Every country has 3 phases at most houses. It's nothing special in Germany.
That isn't true. The OP is correct. Few countries get all 3 phases to every house. It is most common in Europe. Some houses in 120v countries get 2 phases.
Same in Finland, 3 phases in every house.
Same in czech rep.
Power companies can even supply single phase, and neutral is tied to earth ground. For small houses in the middle of nowhere. So much for the GFCI protection on a hair dryer in a home wired this way.
Great video and explanation! Very educational and entertaining!
That was a great video man. I'm a electrical engineer and It helped me refresh some of the concepts I learnt in college, and also I learn some other things too. It's also crazy how you make a shortcircuit almost every 2 minutes 😅

No shit you didn’t learn this in high school. This is college level material. I learned about this stuff my second year in college.
My only regret is that I didn't come across this channel sooner. Really great content and excellent delivery. Plus, the "accidents" definitely help to show the dangers of electricity.
7:27 It sounds like a printer motor. Because of the sine waves, and at 7:36, this is why it reminds me of "Crazy Machines - Die Erfinderwerkstatt or Warsztat Wynalazcy". It reminds me of Lasko and SMC oscillating fans with my favorite parts that match when some fan parts are different. SMC oscillating fan motor covers are my favorite when they have teardrop shaped vents in a circle, and the Lasko fan motor covers are my favorite when they have arched vents on top and horizontal vents on the bottom. The guard nuts, rectangular mountain slanted oscillating knobs, and if applicable, the "0-3-2-1" marking on the mechanical speed control on top of the motor cover unless it has a remote, which in that case, it'll be on the front of the fan (and may have a timer) are also my favorite, but it depends on what parts are intact.
I am happy to see u alive everyday. Love your lessons
Why didnt someone tell me about this guy? he is ***ZAP**** owwww! Awesome.
I like working with 3 phase motors as they are much easier to start. Thank you for posting on this very important topic. This subject is something that is used in most businesses as it makes for smoother power output with smaller capacitors on the output of a bridge rectifier.
Nice motors until you connect them out of phase.😅

Here in Poland, we get 240 volt 3 phase in every home. This way wiring can be much thinner and cheaper.
Is that line voltage or phase voltage?
Phase to neutral is 230V, Phase to Phase is 400V, this is common through the most of the Europe
Is it also 50Hz? North America for houses is center tapped 240v 60Hz. 208v 3 phase is used for the apartment/condo buildings.
Yes it is, but the actual parameters of electricity in Poland is like Tesco Value XD
Not everyone has 3 phase power in Poland. It's common in houses, but in older flats it was common to just have one phase installation for each apartment, but it's last mile problem. Usually every building has 3 phase source available. Although 3 phase is common, there's really no big use for most of us. Only instant water heaters are a common consumer devices that use 3 phases and only high powered ones. There are many 1 or 2 phase heaters. Induction cookers are probably the main reason why most people needs 3 phase installation, but those cookers only use 2 phases anyway. I myself have pretty much an industrial installation and I have a few of big 3 phase motors. Just starting them makes you nervous. Loud and powerful.

Very useful info man, Thanks!
Good job, enjoyable and efficient teaching.
One of the best you tuber educators out there! I wish he was my prof in university. Hilariously funny.
The best reason for 3 phase is the fact that when the 3 loads are equal then the power from the system is a constant. In other words the power is NOT modulating at 60Hz like a single phase motor. Rather, the power is not modulating at all. It is a constant. This means that for a single phase motor you can hear it humming at 60Hz. But for a 3 phase motor (if it was perfectly constructed) you won't hear any hum. This means nearly no 60Hz vibration and thus the motor lasts longer. And the torque output of the motor is also a constant which induces less vibration into the load so the load lasts longer. Some math. Power is a function of the square of the voltage. Single Phase Power=SIN(alpha)^2 = SIN(2*alpha) which varies with alpha Three Phase Power=SIN(alpha)^2 + SIN(alpha+120)^2 + SIN(alpha-120)^2 = 1.5 for any alpha
I heard a sawmill operator say exactly what you're talking about with a grinder that used a 300 horsepower electric motor. He said someone was running frozen wood through the grinder, and the force involved caused the ground to shake, but "ou can't hear anything from the motor, so "you can't tell whether or not it's working hard, but it must've been".
It doesent matter *dab on haters.
You will still get Lorentz attractions in the end windings and magnetostriction in the stator core, both of which can cause humming at twice the electrical frequency.

Lol most of European countries uses 3 Phases system, or rather the system is provided but not often used in home-use
Tesla gave it to Croatia first!
I'm in Australia. I have 3 phase to my home to power my well pump
I am in Australia and the houses either side of me have 3 phase. I have one phase so I am limited to about 100A maximum, and it makes me sad sometimes. New houses commonly have central A/C system so will have 3 phase as standard - you'd be crazy to only have 1 phase installed.
Dude, you make me love being an electrician. Thank you!
Very good lectures with visual demo
I always love your videos. Thank you for teaching me and making me laugh at the same time. Your awesome. 😊
I was watching this while I did my trig homework for precalc. You could say they were very COMPLEMENTARY!
LMAO. This guy is amazing. Instant sub.
240 AC in Canada (and US) is delivered to the house with the neutral tapped from centre of a local transformer (aka split phase). Having a voltage of 203V suggests there is an apartment building transformer taking in 3 ph and and splitting off 2 phases to apartments. (apt A is red-blue, B is blue black, C is black blue, etc), nominally 208V. In my kitchen, measuring both hots gives 240AC (house), and all single phase.
I was wondering why you have 4.6 million subscribers at the beginning of your video...but now you just got one more. Excellent show, very informative and perfectly delivered! Subscribed.

At 4:35 when you say that the AC is 120 degrees out of phase between top and bottom outlets, perhaps that is the case for city power, but for rural power with transformer cans on poles, it is 180 degrees out of phase, since the neutral is center tapped to that transformer's secondary winding, which is what is delivered to the electrical panel.
I couldn't stop laughing at you bro when you connect something I stop breathing. It's a combination of experienced telling us what's not to do and learn something new. Good job brother. :)
You are cool bro.... full of energy... your students will never get bored..
And they'll leave full anxiety wondering when the teacher will finally fry himself.
It was an excellent refresher even for seasoned electrical engineers.....we learned so much so quickly that it was hard to retain the basics from time to time.........After 25 years working i also found the online HAM radio training to be avtremendous refresher of first two engineering terms. But the learning never stops......three years wrestling with $13000 ETAP software even after three training session proves electrical engineering has no end in sight.
Aye to the Ham radio training; amplifier circuits -> IGBTs etc. I am going for my Ham license soon too.
@@solomonthell7589 what are the perks of a ham license how does it teach electrical engineering, arent they 2 different things? They teach igbt no way...?
Great video! I found it very cool and informative.
I love your way of explaining things. It makes sense, because youre not using fancy words.
