7 MILLION VOLT TASER (stun… thingy)!!!

What i don't understand is that you've said that the van de graff generator dropped voltage to 50kV when he touched it, but that's still high enough to procude lethal current. Even if his body resistance would be 100k Ohms, half an amp would still flow through his body, so how is he not dead?

Loved this one. Coming from a background in audio electronics, it sounds like the 500 watt peak power 49 dollar amps they make. Yes, maybe 500 peak just before the smoke or fire starts. Not really useful. Give me AMPs any day to push those speakers. High current, not watts.

Another great video, Mehdi! It's been explained to me that the higher-than-airgap voltages play an important role in "punching through" clothing and whatever else might be protecting an assailant. I can't say for certain how accurate that is, but it makes sense. In the real world, you're not necessarily going to use a taser in open air, or against bare skin. Imagine if someone was wearing a jacket, which may be an insulator, and shoving that between the electrodes. Suddenly, there's no way for an airgap alone to create a conducting channel to the persons body. You have to then consider the breakdown voltage of the jackets material, which could be hundreds of KV to millions. It doesn't matter if that voltage is maintained. It just has to be enough to create that conducting channel for an instant. Also, you mentioned 10's of amps for nano-seconds, but (as you know) a real-world human body has complex capacitive and inductive properties, and current spikes that large in that short period of time seem really unlikely. Again, great video. You're truly one-of-a-kind, and we're all very lucky to have you around.

I think they got to that number through a gross abuse of mathematics. If you use the capacitance equation C = permittivity of free space *area / distance, get a small number out of it (say, area 1 square mm, distance 1 cm to get about 8 pF) and put it into the voltage-capacitance equation V = Q/C with a guess about the charge (say, Q = 7 mC), voila! You get about 7 million Volts. Still completely incorrect, but I couldn't think of any other way someone could come up with the 7 million Volt number. It could also explain how someone came up with those other ridiculously large numbers.

I'm laughing so hard, I feel like I've been tased. But seriously, excellent explanations and info, great stuff Mehdi.

"It is not the fart that kills you, it is the smell". For Norwegians with bad English, this means that it is not the speed of movement that kills you, it's the brutal stop (accompanied by a loud noise). This, however, is not at all relevant to this brand new, exciting video that I got early access to. Thank you very much.

Will you follow up with a video explaining how these devices are able to make these claims of such high voltage?

NateTheOK

Awesome great work yet again !!!

So it's not the volts or amps that kills it's the ohms or rather low impedance.

Thought that saying on what kills you makes a really nice motivational poster: <a href="https://i.imgflip.com/24ftqv.jpg" rel="nofollow noopener" target="_blank">https://i.imgflip.com/24ftqv.jpg</a>

I teach you to make your own!

Oh you little girl, afraid of the DEMONETIZER😈? That's why you have patrons.

So no taser giveaway at the end? :(

I would like to thank my high school physics teacher for teaching me that it is the current, not the voltage that will kill you, and now my whole life has been a lie... Seriously though, thank you Mehdi for clearing this up :)

I smell a new tshirt slogan... 😉

Another great video. Every time I hear someone say it's the current that kills and not the voltage, I picture you coming out of nowhere and immediately yelling and poking them with alligator clips.

... and this is why I am a patron. Excellent video. I had often wondered why these things didn't zap everyone within a four mile radius when operated. I want you to make some kit up to show the waveform on your scope Mehdi!

Great vid!!!!!

Ron Kroetz

you seriously rule! excellent keep them coming, I'm learning more from you than I did at University. lol

Richard Boyce

Mehdi! Youre awesome.

50kV

Don't have anything cheap to blow! Oh, in fact I don't even have the phone thing

ElectroBOOM [Mehdi Sadaghdar]

Still killin it Mehdi

So what voltage is the phone case taser producing? Was hoping to see you place some test leads across those probes to find out.

Very cool episode. I like your passion for voltage!

These debunking videos are so great. I really hope more people can band together on Youtube and other platforms to collectively take down and debunk all these pseudoscience peddlers and blatantly misleading sales pitches.

My shotgun is pretty cool, because it can shoot 9 million pellets into the bad guy

Amazing video. What are police tasers rated at in terms of voltage, any idea??

"Jerry" better look out. Mehdi's on the case.

Cool! Though, I can think of 7kk volts across any distance in the air if generated very quickly. I.e. faster than air ionization and conductive channel propagation. Or if a supply could maintain 7kk volts across the conductive channel, effectively sending Marty McFly to dinosaurs.
