Video: What type of electricity hurts more: AC or DC?

Ouch! Mehdi Sadaghdar answers this question by running electricity through his own body and giving us feedback.

What type of electricity hurts more: Alternating Current (AC) or Direct Current (DC)? In this video, electronics hobbyist Mehdi Sadaghdar answers this question by running each type of current through his tongue (an excellent conductor!) and letting us know what different voltages feel like. Besides being informative, he’s quite funny as well. Please do not try this at home.

For some background, in alternating current (AC), the flow of electric charge periodically reverses direction. The power coming out of your wall socket is in alternating current. Because this current switches back and forth in direction, it pulses. This is why Sadaghdar’s tongue is wiggling at 2:53.

In direct current (DC), the flow of electric charge is only in one direction. You’ll find this kind of electricity in batteries, fuel cells and solar cells. Because the positive and negative terminals of a battery are always, respectively, positive and negative, the electric current always flows in the same direction between those two terminals.

Bottom Line: Which hurts more, Alternating or Direct Current electricity? Mehdi Sadaghdar answers the question but running electricity through his own body and giving us feedback.
