This is one of the reasons we have AC supplied to our home and not DC, among ather obvious reasons. > Edison pushed for the use of AC by demonstrating on a horse. He'd fist hit it with AC and watch it bolt. When caught he'd again shcok it with DC killing it stone dead. No, you won't. Muscles are *NOT* current-direction sensitive ! AC (in a 50 or 60 Hz cycle) only means that your muscles are not contracted the whole time. just about 100-120 times a second. In the time between *you* would have to force your hand open & retreat. I wish you good luck with that. By the way: Your example with the horse does not prove that you will be "repelled" by a AC current, just that AC is not as deadly as DC. And that's because your (or the horses) hart will try to beat in a 100-120 Hz rithm. And that goes better than trying to beat when a DC current constantly pull's the hart-muscle together ... My 0.02 cents. Greetz, Rudy Wieser
