This is a really simple question for the gurus, but still puzzles me. As far as I've read in the online textbook, Current = Voltage/Resistance. If this is so, why doesn't a shock from a taser or a piezoelectric lighter which can apparently reach over 3000 volts kill a man? The higher the voltage with constant resistance means higher current flow, and surely 2 amps (3000/1500ohms of resistance) will easily kill somebody. So, why does this not occur?
