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.
