Amperage is the killer, but as little as 50Vdc @ 50mA $ can kill. AC is roughly the same. The value I have is 23 Vrms @ 50mA. $ I'm told that AC shock survival is lower because 60 Hz interferes with $ the natural beating of the heart ( roughly 60 Hz ). $ Wait a minute, I thought the human heart beat at around 60 per minute. nor per second. ;-). That would be roughly 1 Hz. Yeap ! A very small current going through the heart is enough to fry you. I believe it is in the order of mA's. Due to human body's substantial resistance, you need some respectable voltage to induce that current. Making thing wet reduces the resistance and hence you need less voltage.
