How many volts does it take to kill a human when they get electrocuted?

    Technically, it isn’t the amount of voltage that will kill you if you happen to be electrocuted. It is the combination of voltage and amps that could potentially stop your heart. It would take about 100 mA (milliAmps).

    It’s important to take current (rather than voltage) into account when trying to calculate the amount required to be lethal.  Current is proportional to voltage, and inversely proportional to resistance.  Currents between 100 mA and 1 A are most dangerous to the human heart.  Taking into account the 1 kS resistance of skin, these currents can be produced by voltages ranging from 50 V to 240 V.
