Is 2000V actually more dangerous than 200,000V?
Ғылым және технология
How can lower voltage actually be more dangerous? Well, there's more to it than just the voltage.
It's the amps not the volts that kill, true, but you need the right conditions to enable enough amps to flow through your body to be lethal. 10mA across the heart is generally what's considered the lethal threshold. In addition to the impedance of your body, which is highly variable and hard to predict, you need to know about the output impedance of the source of electricity that's shocking you. Tesla coils can output hundreds of thousands of volts, but have high output impedance. When you get shocked by a tesla coil and create a low impedance path to ground, the increase current flow causes the output voltage of the Tesla coil to drop significantly, because of its output impedance. You aren't actually getting hundreds of thousands of volts dropping across your body. Things like microwave oven transformers, however, have much lower output impedance, and even though the voltage is hundreds of times lower than the Tesla coil, the output impedance is so much lower that it can source significantly more current and is therefore much more dangerous.
Also, the skin effect is a myth when it comes to electric shocks and the human body. The models about current penetration depth as a function of AC frequency only apply to uniform, isotropic conducting materials, like metals. Not the human body.
Output impedance is one of the most important concepts to understand as a high voltage enthusiast and plays a key role in your safety when working around high voltage electricity.

One of the most underrated channels I've come across. Keep making great content, it'll pay off. Very informative and straight to the point, helpful tips and great video editing. Couldn't ask for more
Also you deserve way more views, like seriously you should have at least 15k subs
Dude I've been asking this question for years!! Thank you so much! Subbed!
This was a really good video, thank you for sharing!
Hey man idk if youtube is something you want to make into a career but i know you have what it takes. I looked at your sub count while watching your video and was shocked to only see 1.43k subs, this content is on the same level or even better than other similar channels that have over a million subs. You're doing everything right but maybe not marketing yourself or posting enough idk what the issue is. All i'm saying is, you got what it takes.

Thank you, I appreciate that! I would like to post content more frequently, but I do the best I can with working at the same time.
Great info, champ. Thanks.
So great Video.⚡ Not a lot Information out there on this topic...
Great video! I learned something new!
Great explanation of the skin effect, and its relation to a conductor! Most people explain it in a way that can be very misleading for beginners! Our body is NOT a solid conductor!
The duration of the sparks is also important as it determines the energy. A few amps can pass through your heart when getting a static shock but because the charge and duration are so low and short the energy is only a few millijoules. Great video, I agree with everything you said.
Iv been an electrician for 23 yrs and the amount of knowledge coming out of this and other channels like this blows my mind and it's "shocking!" Lol

Haha thank you! That's definitely a big part of my objective with this channel. To be informative and scientifically accurate, but to do so in an entertaining way, and with real demonstrations.
Van deer graaf generators can make 200kv and 40 A but its only one nano secound so duration counts too
Do you have any fun experiments you'd like to be done in winter and snow? I'm in canada and would love to help

Cool.
The skin effect also doesnt happen much at all in resistive material like skin
Can I contact you to discuss Tesla zenneck wave launcher? There's a bunch of stuff i cant post here. Just gets deleted.

What happens if a transformer is wired straight to the tesla coil and it was powered by AC allowing circulation 🤔

A Tesla coil is a tuned resonant oscillator. You need to drive it at its resonant frequency (typically hundreds of kilohertz) in order for it to work. Driving it at mains frequency (50 or 60 Hz depending on where you live) is not going to work.

@@CoilLabs what would the power be like if it was tuned to 432hz? If the power source is seperate IE not from a hydro line could the power circulate back from the tesla coil to the starting power loop?

I'm going to be honest, the words you are using do not make any sense. I have no idea what you are even trying to ask me. The question you're asking about the Tesla coil frequency though shows that you need to spend some time reading about Tesla coil theory and learn for yourself how Tesla coils really work. That's alright though, it's not an easy topic to learn, initially. There are some really good resources online. These links are some of the best ones that I know. www.teslacoildesign.com/index.html www.hvtesla.com/design.html deepfriedneon.com/tesla_frame0.html www.stevehv.4hv.org/ onetesla.com/tesla-coil-faq www.classictesla.com/java/javatc/javatc.html This is all the help I can provide at this time. Hope you find this helpful!
