Question: how many amps can kill a human? 

Answer: I don't know where the 0.07 Amps came from.  You can be killed by a whole lot less!  0.07A is 70 mA.  For perspective, the GFCI trip level is 4 to 6 mA, because more than that can kill you.  The exact amount can vary by person, and some people can be killed even with a GFCI tripping.\n\nThe voltage is important only from ohms law, the higher the voltage the higher the current.  The biggest resistance is the skin, and that is lower when the skin is wet.
