@acmqqmca that's what skin effect is dude. the higher the frequency the less penetration the electricity makes along the guy's skin. what your thinking of is the sweet spot where the frequency is high enough that you don't feel it but still low enough that it penetrates below the outer epidermis.

>This is NOT skin effect. Correct. Do the calculations for skin effect in a 2cm pipe filled with salt water. The result will suprise them. The electric heating goes deep. Also, their claims make no sense: the outer skin layer is nearly nonconductive, so "skin effect" currents in outer dead layers would be insignificant. Why do many books say otherwise? It's a "galloping error," caused by authors who copy information from earlier textbooks.

This is a textbook error! With induction coils, metals display significant "skin effect" but human tissue does not. Electrolytes are too resistive. Do the calculations! Also, nerves are in the outer live skin layer, so "skin effect" would cause extra pain. In fact, high-frequency currents cause no pain because nerves only respond to few-KHz frequencies and below. The heating goes deep, and can warm fingers and cause pain in arm joints "Tesla Coil arthritis!"

me neither

I think the guy at the back lights the bulb with the electricity running through his skin or something..

Hmm... I don't get this one...

This is NOT skin effect. The guy just doesn't feel the current flowing trough his body because of its high frequency. This experiment can result in internal burns.

In fact, the "SKIN EFFECT" is the current flowing with a very high frequency, so far you are right. BUT due to Maxwell's equations and the high frequency the currents are expelled from the body volume to the body surface -- the skin. Therefore the name. :)
And you do not get any internal burns if the frequency is high enough, in fact your outer skin layer is dead anway. ;) But please DO NOT try this at home with a frequency generator!!!
