Could be fatal. Some charts put this level as low as 65mA... A couple of years ago I had a bit over 12V and 100mA run through me for some time. I must say it was exciting... 250V mains, whatever amperage that is. Fibrillation? Certainly. Burns? Not external (good contact), but the current did internal damage to the bones in my wrists, which are never going to recover fully. -- Andrew Grebneff Dunedin, New Zealand 64 (3) 473-8863 <andrew.grebneff@stonebow.otago.ac.nz> Fossil preparator Seashell, Macintosh & VW/Toyota van nut |
