Funny and interesting video comparing the physical pain of AC versus DC on a human.
Through all my years of being shocked, I somehow came to the understanding that AC (Alternating Current) hurts more than DC (Direct Current). Then somebody, which I don’t remember who, told me that the body has capacitive properties and lets the AC electricity through better. I don’t know how true that statement is, but from experience it somehow makes sense. If you hold on to a 50V DC voltage with dry hands, you won’t feel it as I experienced. But as soon as you switch the same voltage on and off at high speeds, such as 60Hz, it will shock you badly.

Of course nothing beats this Epic Rap Battle which I have not been able to get out of my head all week (Telsa vs Edison). If you didn’t already know, Edison was a dick. Also check out the behind-the-scenes video that shows how much work went into it.
