I really appreciated the extra effort put into the video. Made me laugh at a few times, while learning!
Incoming "how is this comment 1 day old when this video is 1 hour old???" replies
sir can u explain why does the voltage increase in step up transformer

I can, but only particles in _brownian_ motion
But ampere circuit law!! The current needs to penetrate the amperean loop!!

Aah, polarized electrolytic capacitor. Mehdi's favourite passive component, being one of the most explosive of them all.
It sounds like something I would make up as a joke, imagine an electronic component that explodes if you plug it in the wrong way
Ceramic capacitors are more explosive lmao
Then I guess you haven't seen tantalums, @@renzevenir4853. They don't vent, nor burn. Just pure explosion. Had one blew across my laboratory. They often randomly explode on their own, which increase the excitement and why you don't see them very often in circuit.
When I was in college, I was working at an electronics repair shop. Business got slow and people were getting their hours cut. During slow periods, we worked on returned equipment, from local consumer electronics stores. One of the techs, who worked in our cordless/cell phone department, was trying to be a ‘super tech’, to impress the owner. The problem, was that I knew this guy since high school and he didn’t know crap about electronics. He got his job, at the shop, by using my name. (Don’t use people’s names, unless you ask them!)
Anyway... he burned through all of the work in his department and started on the work from my department. (Home audio) We weren’t exactly dragging our heals, but we were trying to make the work last, until business got better. Not this guy, though. He started blazing through our work, as well, threatening our hours. The worst part, was that he wasn’t even repairing anything. Even if he was, it was threatening our hours and we needed to slow him down. We tried explaining this to him, for our benefit, as well as HIS. He went to the owner and said that we were telling him to slow down. A totally ungrateful douche, right? This wasn’t going to go unpunished.
Commence “Operation Bang-Cap”!!! In about every third stereo receiver, we opened it up and reversed one of the large filter caps. Then, we sent them to him, for repair. About twice per day, one would explode. Sometimes, even bulging the case of the receiver. 💥 He would be crapping his pants, while we would be peeing ours. 😂 What eventually slowed him down, was that all of the phones that he ‘repaired’, came back, with the original complaints. Every. Single. One. Of. Them. Now, he had to actually repair something, which he couldn’t do. This ended up getting him fired. Morals of the story: Listen to the people around you, when they’re trying to help you, and you’re threatening their pay. Don’t take a technical job, if you have no idea what you’re doing. Don’t use people, as references, if you’re an idiot.
What a story, @@Willam_J. Reminds me of my high school project back then. My friend was such a douche, that I got tired dealing with him. I ended up switching the 220/110 switch on the PSU on his project. There were some nice smoke and explosions. He never figured it out it was me, till now. Still have my own recording of the explosion, can't get tired watching it over and over again.
This happen about 25 years ago but it never gets old to me. I was at college and we had this class about electronical technology, which was all about circuits, diodes, resistences, capacitors, you name it. There were a few hours of theory a week and two hours of practice. So, we were in the lab about to practice with capacitors, the electrolite kind as in the video, and when the teacher started talking it went like this:
Teacher - Remember to correctly polarize your capacitors because otherwise...
Somewhere in the lab: BBBAAANNNGGG!!!
Teacher - ...THAT happens.
xD man I wish I was there to see all the action 🤣
:DDD When I was in school every electronics class started with capacitor fireworks
When i was in school the ceiling got lit on fire lmfao
I guess it happened in 1995

The physics teacher I wish I had, yet never had.
This was so informative, clear and witty. You are very good at explaining. THANK YOU FOR YOUR VIDEO!
Also, with regards ti current trailing voltage with 90 degrees, does this have anything to do with the fact that a capacitor used as an audio crossover delays the audio signal with 90 degrees?
The physics teacher we all have!
I have a master's degree in electrical engineering, and I still enjoy watching electroBOOM. I've been watching him since my first semester of studying electrical engineering. I really enjoy his entertaining ways of conveying information. He really knows his stuff, and he's a great character. I wish him the best.
Well never did get the masters (changed field after few years), but I know the facts are there and that the representation is really well made and entertaining! Just hope people don't get idea about getting stupid zzapss like these, because it's not really good for you, especially if you don't know what you are doing!
I think the ‘stupid zaps’ are exactly for that purpose of letting people know about those mistakes. He generally explains the mistake afterwards but, I can see the mild concern there lol.
I have a Master in Electrical Engineering too and yet i learn some new stuff from this guy, never stop learning for sure.
I have a dummy’s degree in malectoral mengimeering and even I love it! 🤓
4:07 this was better that all my physics classes at college.
😂
That's sad.
Behind the charming personality and hilarious explosions, there's actually very useful and effective eduction here. Love this guy
"eduction" lol
6:20 I haven't heard this in a long time now lol
Its like waaeeeeaaaeeeaaeee
You can really hear the progress in ElectroCute's piano playing over the years. Love it!
Also I really liked all the extra production work that went into this one, the jail scene was funny.

Thank you for the comfy videos Mehdi. I put your videos on in the background when I work on microsoldering/fixing laptops and other components I have. Very good memories sitting on the floor of my apt working on this stuff while you're in the background teaching me at the same time. Even if it's something I know, the way you present is unique and captures my attention easily. All the best health, happiness in life, thank you!

2:47 - What did I tell you?
I like how you can freehand draw a perfect sine wave then perfectly freehand another sine wave 90 degrees out of phase, but can't draw a straight line to save your life 🤣
yeah, it's funny :) although, I would say that the sine is not perfect either, but we perceive the imperfections (bends) in a straight line much more than imperfections (wrong curvature) in a sine wave.
🤣🤣🤣
I really love this video series! I have always been fascinated by electronics, but university has not been the right path for me. Somehow you are able to get concepts into my head better than university professors
That plexiglass/magnet training model is brilliant. I need to build one now.

That's him falling not the camera.
Why didn’t anyone explain it like this 33 years ago when I studied this in school?
You studied this in highschool. Or maybe us younger generation get put through this bs
Yeah when I learned this I had to take integrals and derivatives and use matrices to model circuits.
Because schools can't afford a PhD scholar.
Because your teacher probably wasn't an electronics enthusiast.
Homeschool your kids!
Still same today, man...
6:11 I like how he have to rectify himself😂
These are truly amazing lol i’m learning a bunch of minor differences as an electrical engineer and telling dad all about it haha. Like about EMF and Voltage and why voltage is called potential and what not. The best so far has been talking about drift velocity. Awesome stuff.
6:07 i'm crying from the laughter.
Same here dude 😂
"Some idiots!" He has good self esteem.
He in his some previous video told this and did same face...
Still laughing though...
sure Mehdi sure... 7 years in... and now we finally know how capacitors work XD
It took 7 years to prepare people for THIS!!!
@@ElectroBOOM Fellow untrustworthy accent-man replied to my comment! Life has some meaning after all
sir can u explain why does the voltage increase in step up transformer
@@ElectroBOOM can you make a video about transistors. Im struggling to figure them out
@@vinayakchakraborty8996 I'm no expert, so take my response with a large grain of salt!
It's about the ratio of input/output windings. Because there is no free energy, the total about of energy is the same on both sides (assuming no losses), so the wattage must be the same on both sides. This electrical energy induces a magnetic field (which is what actually does the work of transferring the energy)
In the presence of a magnetic field, the more wire that's exposed to it the stronger the induced voltage is in said wire.
Remember that P=V*A and that there is no free energy, so
P input = P output
V(in)*A(in) = V(out)*A(out).
If there's more wire exposed on one side of the transformer, that side will have a higher voltage. But in order to maintain equal power, the current must decrease on that side.
Education + Comedy + ability to make science interesting = ElectroBoom. I just cant get enough of these videos.
I feel like I understand capacitors less now, but I love watching his videos
0:43 is the best part, i'm crying!

"If there is any capacitor , it must explode." -Mehdi S.
Mehdi's law
Capacitor must be Muslims.
You wrote "s." cuz you cant spell Saldhautjalaldl4slalaharal
I appreciate the various demonstrations, analogs, models, and diagrams! You'd stated that these videos are less exciting than usual but I have been loving both equally!
I really enjoyed and learnt from this video! I hope in the future you could help explain about AC Circuits, resistance, impedance and inductance and all that. Thanks!
Mom: stop watching memes and study
Me: Trust me I'm studying
Hahaha
And it's TRUE too....
If I were your student I'll always come early and never absent to your class.
Yeah Mehdi is amazing at explaining stuff. You can see the passion he has. Wish I had a teacher like him. It's rightly said
"If you don't like science, you probably didn't have the right teacher."
It's the learning of the future
I want to see behind the scene, did his wife and daughter actually see him acting like that?
I'm sure at least one of them helped with filming.
His wife probably has premium life insurance
I really enjoy your videos... you clearly have great knowledge of electronics; clearly love and enjoy each and both this topic and sharing knowledge with others; and present this information in a detailed, fun, funny, interesting, clear and concise way. Thank you!!!
Thank you so much for the video! I'm looking forward to the video on inductor coils. I hope you will make videos about transistors and diodes!
I want to appreciate how what I thought was just all his dumb funny vids have actually helped a lot in my Physics exams. Thanks Mehdi!
9:27- 9:50
Ah yes! I finally I understand what my science teacher couldn't explain
Thanks Medhi! Looking forward to the next 101 video
I've got no questions remaining about capacitors now, and I found this after watching 20+ most watched videos on other channels. This is by far the most informative & fun electronics video I've ever watched on YT, covering physics, math and electronics around capacitors. Great job man, and thanks a lot for putting tens of hours of your time & effort & thinking on a 10 min video. Did laugh out so loud many times when I was actually learning something new, you do have a great talent for teaching!
This is best explanation I've seen on the net especially the end explaining the lag\leading relationship. I will definitely refer people here in the future!
Teacher: Electrons always take the easiest route to travel
Me: what do you mean can you give an example?
Teacher: Let's say you have a cell with a wierd guy and the cell next to it is filled with girls
Me: okAy i GoT iT
That whole electricity takes the path of least resistance is not true. It takes all paths available. The current is just the inverse of the resistance.
@@mgzukows Yes, but why did a man stick a resistor on his stove?
Because he always wanted an ohm on the range!
PA-DUM, TSSHH!!
well this is not really true, if you have two paths to ground, with different resistances, electrons will go both ways, but less will choose to go towards the higher resistance
@@mgzukows id say it actually does but the flowing electrons take space too so the others will go over higher resistance because for them its the lowest.
@@Tremor244 It's absolutely true, because if it only went to the path of least resistance it wouldn't go down the other path at all.
Like I said electricity flows down all paths available. The current is inverse to the resistance.
It's basic Ohms law.

Very good work! you manage to explain exactly what I was searching for and "may I ad" in the most logic and understandable way. You sir deserve a medal! thank you :D
What an excellent video. I've been doing hobbyist electrical design for 40 years now, and this is the first time I've had a really clear idea of the principles behind capacitance. Your explanations are clear and make complex principles seem simple. I'm looking forward to inductors!
ps. we used to blow up electrolytics in grade 10 electronics class by ramming them into electrical outlets! For those reading, this is Very Bad and Dangerous so don't do it (but it's loud and spectacular).
Can't have more than 2yrs experience if this is new for you.
We did something similar: we charge capacitor battery and put screwdriver on it. It was really loud and fun thing to do.
If Diodes are like the one-way valves of electricity. Then I think Inductors are like the engine flywheels of electricity. They resist sudden change. I wonder if he will use a heavy or wide flywheel model?
9:58 I wonder if Mehdi started to play BASS...
Davie504 wants to know your location

*Amazing Editing!*
I saw your video everytime and I also didn't know your videos are over I thought that the video was small but than I realized that your videos are of full of knowledge so I don't think about time while seeing this videos!!
In my 3 years of college I was never told why AC passes through the capacitors or DC gets blocked. All It took was a guy who tries to shock himself who has a RUclips channel.
thats y the capacitor gets charged and discharged in positive and negative half cycles of AC respectively!!
_appears_ to pass through capacitors. The part that I've never heard before is the rate of change part! Makes total sense why the can be used as a high=pass filter - the higher frequencies just can't "get through"
The fuck kind of electrical degree are you studying..?
Once you learn beyond what you were taught, you will again say why was is never told about this. You were for example never told about Tesla's longitudinal electricity which is different from AC and DC. Google "Transverse & Longitudinal Electric Waves and Tesla’s Longitudinal Electricity - Eric P. Dollard". Also youtube search "Eric Dollard - History and Theory of Electricity" to learn stuff about electricity that is not taught in class.
Usually this is taught in school and in much more depth in college. You must have chosen a better college 😜
3:20 A very Schottky diode.
I myself prefer a Frenkel diode personally.
yes bro thats a schottkey diode
I have to say, i worked as an electrician for 10 years now and not even during training or later the concept of capacitors came to me. But now with your video it finally clicked in my head! Thank you mehdi!
The funny sketch for trying to go to the other side was the best I ve seen many videos but yours was the best understanding exactly what happens really thank you !!!!
Sir, I am a electrical engineer as well, & I am totally impressed by your work and safety precautions you spread through your videos.
Great work!☺️

"some charge went into the capacitor in no time, and that just doesn't happen in real life"
Quantum physicists: yeah about that
Einstein to quantum phycist: watch it pal, I know what you did to your cat...
Quantum capacitors, can charge random capacitors all over the universe. Real wireless charging.
@@En-Pea-Sea
Wouldn't you need to bring the charges used together before tho so they can get entangled?
Or can you entangle particles lightyears apart from one another? It seems like that should violate C, our Cosmic Speed Limit for all Causality.
@@Broockle i think for now entangle particle that have lightyears distance is still hypothesis and still a pure math equation
@@kecoaxx
well.... there's no practical experiment confirming that I guess..... fine
Wow! I have to say that I learned more about capacitors from this 10-minute video than I did in my entire 4-year electrical engineering degree. You did a great job explaining the current formula without saying the word 'derivative' and also a great job explaining why current leads the voltage. I hope you keep up the great work and that you have a fantastic rest of your day
You're a bloody legend Mehdi!!!! Best explanation of caps that I've ever seen. Looking forward to inductors. Big love from Ozzie land!
Explanation through the superior mathematics is easy understandable and great. You are the best, thumbs up for you!!!!!! When the similar for inductors, I almost have no patient!
The thing responsable for 90% of explosions in your channel!
This is one of your best videos ever! SO many different bits, so much weirdness, but seriously detailed explanations and a few explosions as always, perfect video
I see this as one of the best channels on youtube. Thank you so mutch for you sharing, Im learning alot :-)
Hope to really understand capacitors one day, so I can build myself a capacitor pack for an ebike (dragbike).
The output must be around 48v 10Kw (10-15 seconds), might just be easier building a LiPo pack.. Time will tell...
Hey Mehdi, I've seen every single video you've posted so far and I've gotta say.. I NEED MORE OF ELECTROBOOM 101 IN MY LIFE !

You explained this better and in a way that was easier to understand than I learned in 2 weeks of Physics II at college. Fantastic!
I like how this is one of the best educational channels on YT and is a great comedy channel as well.
This is great. I’m taking an EE101 college course at the moment and you’re insight is really helpful.
You're gonna be amazed at how easy the basics really are. Then, you're going to get blown away by how complicated the advanced stuff gets. There is little in between.
You also might be amazed at just how much stuff friggin' diodes get used for. I'm hoping he does a video on those.
Just goes to show that a good teacher is more effective than an expensive college for learning new topics.
Most of my uni professors would drone on with a monotone voice using outdated powerpoint slides in such a way that even the people most interested in the topic still got bored. If I had a teacher like Mehdi though, then I'd be engaged in learning no matter the topic
As a high school physics teacher, I find your content help improve my teaching skills a lot, great work! Thx!
Excellent video, man. As someone who (ironically) is good at physics but struggles with the application of capacitors- you made an awesome, concise and entertaining video! Thank you
Thank you Mehdi Jan. This was the best explanation of Capacitor I've ever heard!!!

Even after attending so many theoritical class I never understood Capacitor fully! But your 11min video made this sooo clear thank you Mehdi!!
God, you should be a professor.
As a mechanical engineer who hated taking the compulsory courses in electrical engineering, you are a sight for scared minds.
I got suspended from my school for sticking capacitors in the outlet
I did the same with a Lego motor. In 240v outlet, = Big bang! like a gun shot, but managed to blag that I did not know what happened and got away with it!😁

Wow and i thought i already knew how these worked. I appreciate the extra effort i seen in this video and the thought that was given in making things more accessible to a broader audience.
Gd to see ya electroboom! I made my own cap a few days ago lmao! I hooked it up to my cap meter and it was like 9nf. When i cut it in half it went exactly half. Almost lol. 5nf. It was really cool. I made it with aluminum tape and a receipt. Worked gd and was a cool lesson!
"Of course, it only takes a couple of seconds to charge--"
