I like how this guy manipulates "controlled" explosions and accidents to teach electrical safety and proper handling of high-voltages which can help many amateur electrical enthusiasts.
He deserves more subscribers!
MasterL Player it's kinda silly but it's a clever way to show what and what not to do. He has these controlled “sparks” that hurts him but doesn't actually kill him.
And he's doing it waay better then every filmmaker out there
I wonder how many were not controlled.

"I let it cool down for a while AND SHI*!"
Makes me laugh, every time.
Depending on what part of the sun you are talking about, 500 times hotter can be anywhere from quickly dead to instantly dead. That resistor might have been as hot as the sun's surface, but not hot enough to give off so much light that your skin cooks on top of your eyes.
@@vinnysworkshopif it was that hot, it would ionize the air arround it with such energy output
Oh and it would instantly vaporize the resistor lol
@@DatBoi_TheGudBIASYeah, you're right. Overexposure might be why I might've guessed it was as hot as the surface of the sun. It still might be hotter than the surfaces of cool red stars though.

Yeah whenever i hear mention of a rectifier of any kind i hear Mehdi`s voice in my head say FULL BRIDGE RECTIFIER!!

*gets shocked by the capacitors*
I believed he explained that the palm of his hand is more sensitive than his finger, and he also touched the output with his finger on purpose while with his hand was accidental.
capacitors gave him a short pulse of DC. the capacitance of your skin is what makes AC able to flow through it. DC cant flow through but put a short pulse of DC thru a capacitor and it'll go through.
@@polymetric2614 I don't understand, why the DC didn't hurt him but the capacitor did when both have the same voltage?

1:33 That spark is caused by a inrush current of capacitors. Please remember: Capacitors can't change voltage instantly! To limit sparks, you need a NTC thermistor.
cristiano raolda s ucks a t baske tball
Why using a NTC resistor? Why can't we use a standard resistor? (I'm just curious no offence! ^^)
@@wuukaa9079 that way, once you start the circuit it's cold and limits current and holds the inrush current, but as the circuit runs the resistance drops to allow the circuit to run more efficiently now that the capacitors are already charged, this setup is common on Desktop PC power supplies
@@aurunemaru alright! It's a way to reduce sudden drop of voltage on the mains, avoids sparks when you plug and smooths up the start up charge for the circuit if I got it well!
Thank you, I always saw those NTC resistors in many switching power supply and such.. thank you :)
or can we limit the current with resistors , just before the C ?

I've lost count of how many times I've watched this video just because of "FULL BRIDGE RECTIFIER"
Easily my favorite ElectroBOOM video.
I failed in electrical engineer degree. I wish you were my teacher sir. I respect you a lot. You take shocks to teach us.

@@elephystryidiot
A full bridge rectifier converts AC to DC, and an inverter converts DC to AC. I would absolutely love to see just a chain of rectifiers and inverters for the fun of it.
I'm drawing a schematic for a circuit I call a CATR (Current Amplifying Transistor Rectifier) right now. This is similar to a full bridge rectifier but it uses transistors instead of diodes. This keeps the DC voltage output the same as the AC input voltage, but the DC output will have a larger current, which is determined by the beta value of the transistors. Low-power applications would use signal transistors, but high-power applications would use power transistors.
@@coastersaga where could I find your schematic
@@coastersaga Unless I've misunderstood you, what you're describing is actually impossible. If the output voltage is the same, but the current is higher, then your circuit would be _producing more power than it's consuming,_ which would violate the laws of physics.
The only way you can produce more current is by reducing the voltage, or vice-versa.

dry skin v. wet/sweaty skin, resistance changes by orders of magnitude... Besides he fakes a lot of stuff for effect, not dumb you know!
Actually he doesnt fake most of the incidents, they are scripted of course but not faked. He surely wouldnt put himself in extreme danger on purpose but the things that happen arent exaggerated and could happen exactly like this. Im quite sure everyone has been zapped by a high voltage capacitor before, whether being in a camera or a bug zapper or any powerful power supply and although it sounds funny, it indeed is dangerous and you should always discharge them.
zapped by a discharging capacitor i guess

"we are safe now" famous last words
I clicked this video for educational purposes only, but seems like i was wrong there was a bonus tip keeping the viewer entertained while learning.Really enjoyable keep up the good work.
I feel like this is the video that really launched Medhi's TH-cam career
good video. A story of my own fuckup:
I was doing work on a small electric car which is a two car-battery 48v system, and I was trying to rig up a shunt resistor on the positive rail and probe the output to see the current.
The car is isolated from ground because it's running on batteries and is up off the floor on rubber tires, so not a problem to attach the ground of the probe to a point which is right on the positive rail. I'm sitting in the seat of the car with about 4 alligator clip leads draped across my lap and doing some tests while looking at the scope on the bench. As I'm free-running the motor without a chain the vibration makes the car roll back just slightly and the metal frame touched the apparently grounded metal wall behind me. The wires in my lap light up and some stuff caught on fire with a bang.
Cool Story bro👍
just give a fucking TLDR !!
TL;DR the walls are grounded, it blew up.

You can't use any diodes to make a rectifier because the diode has a specific voltage and amperage rating. If voltage or amperage exceeds its maximum value, the diode will die shortly and conduct in two directions. So don't forget to look at its data sheet.

I love your videos sooo much, you can make even the most boring things seem like the most interesting.
I've been watching these videos since I was in high school and now I'm a systems engineer and came back to this video because I needed to refresh my circuit knowledge for work XD
I clicked for it. I really did. Mehdi made me wait a *full 2 seconds!!*
Dude, your videos are great, you are hilarious and you explain things in a way I can understand, could you make an induction heater and explain it's components and how it works ?
I think the best "rectifier" I made was... I used a center tapped transformer, with 4 capacitors and 4 diodes, to make a dual rail voltage doubling rectifier... though it was probably only half wave, it did what I needed it to do.
Does anybody else here have no clue about anything he talks about, but continues to watch his videos because of his priceless reactions?

So 170V DV doesn't hurt... Until you unplug the damn thing and touch the capacitor which have only some of the 170 V DC.
Why is it so ? I also have that question.
My guess is that the current spike of rapid discharge of the capacitor behaves similarly to AC which passes through humans more easily.
Because his palm is more sensitive.
@@chinmoytahbildar3278 It is NOT so. You will feel DC voltage from 45V upwards, depending on the conditions.

Here after LTT video where Linus disappointed me by not pronouncing it correctly.
DO NOT ATTEMP ANYTHING HE HAS DONE IN THIS VIDEO
Oh you bet I'm going to attempt it. But I'm a third year electrical engineering student so I think I'll be ok.
Teach me for skins
Okay, I won't blow a fuse
anything? why not? Don't do the things he is showing you it is wrong with a visual example then an explanation.
A full bridge rectifier is fine to make, but take the proper precautions, do it the right way, and learn from his staged mistakes so you don't burn down your house. That is the whole point of the sparks and shocks in his videos.
I don't know how to attemp anything; but I will surely attempt whatever I wish.
How about you fix that stuck caps lock key first before you give anyone advice; and cut back about 90% of your stupid doge icon's diet. That is one fatass dog ... and if you can't feed a dog properly, which is pretty damn easy, won't take your advice on anything more complicated.
so you probably shouldn't try anything, maybe not even getting out of bed, you might get hurt; though you can get hurt staying in bed too ... just check yourself into an institution where they will provide safety for you and freedom from having to think and problem solve, listen and use common sense, you won't have to bother with those skills. You definitely don't have them if this was your conclusion after watching your first ElectroBoom! video. I hope you get help, so next time you watch something like this, you can understand it and not be so scared! Poor thing. Life is full of dangers and you probably think the warning signs are examples and yell at people not to throw themselves in trash compactors because the picture shows someone doing it and getting hurt and the latter part goes over your head that the it is instructing you on what not to do.
Good luck in life, you'll need it with that attitude and lack of comprehension skills.

I'm only here to see you hurt yourself in order to be concerned if you're gonna be ok.

Some nights, I've got to visit here, just because I've not seen you, Mr. Boom, jump from a shock, and need a cathartic release. Thank you very much for this. Best "full bridge rectifier" video I've seen.
It's FOO BRIDGE REKTIFIA!
You jumped at the end from residual capacitance yet held your finger across it earlier to show that the DC voltage wasn't particularly dangerous. Hmmmmm :)
Yeah, because DC from the output and DC from a capacitor are two different things.
Omkar Pradhan
why? more voltage?
Large amount of charge delivered in a short time through a capacitor.

cool, ta :)

Silly Mehdi, if you don't want any ripple at the output, just short it to ground! No ripple, no deviation, just a clean zero volts!
1:40 JUMPscare alert
Hi Mehdi, could you explain why you get 170VDC over the cap even tough the max amplitude of the FULLBRIDGERECTIFIER is 120VDC at 1:00? Thanks, really love your videos!
+bume nicläs The input is 120VAC, which means it has 170V peaks. And through bridge rectifier they result in around 170VDC.
Thanks for the reply, so the 120VAC is RMS?
bume nicläs yes
+bume nicläs VAC * sqrt(2) = rectified and filtered
120VAC*sqrt(2) = ~170VDC

I'd be more worried if your heart rhythm was a sine wave lol
Normal heart rate? That is clearly a monomorphic ventricular tachycardia, that's not normal, and it's the rhythm, not the rate. Also, we refer to "flatline" as asystole.
@@LunaWunaNo, monomorphic ventricular tachycardia can present with a pulse unlike asystole, and even pulseless monomorphic ventricular tachycardia is easier to resuscitate since it's shockable. To conclude, monomorphic ventricular tachycardia is a better rhythm than asystole since asystole isn't shockable and has low survival rates, however, monomorphic ventricular tachycardia is easier to resuscitate since it is shockable, can present with a pulse (and if so, can be controlled with antiarrhythmic medications alone, or DC cardioversion, as opposed to AC cardioversion which is not recommended.
