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

I appreciate how you intentionally mess up and make sparks to show us what not to do.
@ElectroBOOM has only 8-9 fingers confirmed
@Dylan Davies He used new leads because he damaged the old ones.
YA I ALSO NOTED THAT
@Mike Hale LOL, this comparison is hilarious. Look up who Mr. Wizard was. Cody from YouTube is, and never will be, anything like him. Ask his ex what kind of guy he is.
I did that once too. :) never again
I hold my breath every time he connects something.
lmao
You be like "Owh heck nah man he's gonna explode that thing just like in the other videos". And its still gets me every time.
same
@William gaming200 - I think his tongue has been hit by three phase - same as his eyebrows. Mate: take time to breathe.
Haha, or at least prepare mentally so that you don't have to be quite as startled, huh?
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!
It's because the professors at the universities don't really understand what they are teaching. Those who can do....
@N I 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 IP, 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.
+you got da boomb
An electrician with a sense of humour... A true blessing...
I really love to see him with all those fireworks, can't wait to see him sticking wet fingers into the mains sockets. 😆
EE
Haha this theory is way above electrician pay grade
Haha im an electrician and this is standard theory I learnt.
Shocking
In 11 minutes, you've taught me what an entire semester of electrical engineering couldn't.
ElectroBOOM: Promotes 3d printer
breaks
His knowledge about electricity is soo high, he became immune to it. Lol
He gets high off electricity.
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!
You are in for an electrifying treat.
That's correct... I can't believe that I haven't heard of him before....
Same here, except I just discovered him through the AC vs DC video
yours*
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.
I dont know why but this is the only implementation of a dab that doesn't sicken me.
Why didnt someone tell me about this guy?
he is **ZAP*** owwww!
Awesome.
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.
LMAO. This guy is amazing. Instant sub.
2:10 DAB ON HATERS
Mehdi: it hurts to be this hip
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.
You should have a show on Netflix. You're infinitely more qualified than Bill Nye.
To be shot? Probably. It's owner is an idiot.
Bill Nye is a very accomplished engineer but Mehdi is a much better teacher. Bill Nye is also trying to teach kids simpler subjects. The inability of people to look past their own biases to judge others always baffles me.
@Ambesh Pratik now days bill nye does the exact opposite lol
(instead of teaching science, he lies about basic biology/psychology just to sound "progressive")
@Frosty. I mean, he does have established science to back him up
@Frosty. Why don't you enlighten us all on the truth about biology/psychology?
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.
@mbo191 We have only one phase. The second wire is neutral. There is no potential between neutral and ground. In the TN-C (Which is in the most older buildings) network there is only Phase and the PEN wire. PE and N are connected right in the socket. The PEN wire is grounded so it does not have any potential. In the TN-S network the PE and N are separated. But in the main switchboard those are again connected to PEN and grounded. The TN-S is more safety and allows to use the residual current device.
@pasparinho you can change the original 3 phase motor with a single phase motor.
In Sweden, all buildings get 3-phase 400V. Some older apartment buildings split that up though so the apartments only get 1 phase 230V.
My current apartment have all 3 though.
Back then they didn't have transistors so no DC-DC converters, the only way to really change voltage up or down was by using transformers. Transformers can only be used in AC circuits so AC was able to attain higher voltages which greatly increased efficiency. Also on the consumer side, it was much easier and efficient to step the voltage down to safe levels with transformers.
Huh, today I learned. Thanks.
8:58 "change" was inconspicuous added 😂✌
nothing like getting zapped every 5 minutes. the thrills!
J2wjwu iofjjkioooooudjkkii there uippppp only one
I love how I can learn and laugh at the same time. 👍
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.
3:07 here we have... BOOM!!
1000% better than my teacher
Perhaps get your lecturersto create some sparks or stick wet fingers into mains socket for some laughs.
10000999999990900900.....to infinity times better than my teacher
absolutely
i know its just a joke (mostly lol) but don't be too hard on teachers.
they have to do it live, and they have to do it again and again. Usually to an audience that isn't super stoked to be there.
It's a very different animal
3:06 'Ahhh it's hawt' moment.
“Its like a self healing device” hahaha
I never laughed so hard dude I've been binge watching your videos! 😂😁💀💀
"I need a purrrrr of wires"
I have a degree in electrical technology, but I feel like I understand this even better now. You explain things much more clearly than any of my professors did.
Clinton how is earths frequency measured???
GordieGii what is one thing he is incorrect about???
@sd samuel Explaining a concept clearly and understanding of the concept are directly proportionate. Ultimately, if the teaching uses very good methods, the understanding of the subject matter will be strong.
@sd samuel Amen
@John Bond And phased in in AC.
0:16 he puts dots so that he could have a good illustration
interesting, entertaining and funny, keep it up
4:30 who else was waiting for the oscilloscope to short out? Lol
Simply brilliant. I had to watch it three times I laughed so much I missed the rest. Priceless and so educational. A golden nugget of YouTube.
His 11 min video about 3 phase AC made me understand it better than when I took it for 2 months at school.
I spent four years at college but still confusiom
i'm curious how many hours does mehdi took to understand this thing.
maybe you have spent all the school time on snapchat
Damn chicka
In school? U sure?
@Buck Rogers Hey Buck',, I am hearing you man!
In my studying days, sometimes I used to think that Edison should had electrocuted Tesla instead of elephants
Just discovered this channel. This guy is playing mind tricks :)) i don't have a background in electricity so its great to learn this stuff, with added eccentric-ness :D
8:02 apparently this is the sound of someone hitting his fingers on a spinning fan.
This honestly answered EVERY question i had about 3 phase AC
every time you plug or touch something I close my eyes. LOL
Yes. I watched the remainder of the video without volume after he shorted the first time.
though we expect something like that... but where... when... how... why?! then same thing... close my eyes
@ bluetorch13
hahahhahahahhaha
I had a girlfriend that used to do that in bed and it was a complete turn off. lol
@mweezy hahahhaha
Your T-Shirt is AMAZING!!!! I want!!
Also, you're way of teaching is both captivating and entertaining!! Keep up the good work maN!
"its like self healing device"
6:22 haha now we know the power of your stand you fool
Sometime I used to have drop in voltage back home, so i would change numbers in every phase and voltage would comeback. Now I know what i was actually doing 😀
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.
Not surprising, considering that Germany has historically been a very industrial nation.
@LBGST zockt jep.
Most developed countries has 3 phase to all houses even the smallest apartment..
@TeslaTurk Not like in Germany. Small houses (less than 5 households) in Turkey are only connected to single phase power.
Der E -Herd ist normal auch im Stern geschalten
It’s so ElectroBOOM can get shocked 3 times as fast!
Am I the only one who thought he was going to make an infinite energy joke with the two motors? Also...
Don’t forget not to mix the black and white
1:58 HALLELUJA! Best edutainment channel ever.
...german electical engineer heart just melted...
VDE approved!
Spark man. Keep it up bro. I laughed every time when a spark occurred.
First one to say three phase needs 3 FULL BRIDGE RECTIFIER.
Paetrions get 1 day advance
3-phase bridge rectifiers already exist, son.
League Of Gamer [Fauzan Gaming]
I guess its related to difference of time zones between the viewers,
I made just a guess I'm not sure
EVEN FULLERRRR BRIDGE RECTIFIAAAAHHHHH!!!!!!!
Only if you are needing DC.
10:04 giveaway time
I love the way you scream like a little girl, LOL, appreciate very much your video and in depth explanation

Hi ElectroBOOM can i just say that dabbing is outdated even when this vid was uploaded
sorry is this sounds angry
all it was is to advise
