    Body Resistance

    If 10mA are "lethal", what voltage (V=IR) would be required to produce the current through your body?

    i think i read somewhere that you can assume human body resistance to be 500 kilo ohms. This will ofcourse vary depending on the conditions (i.e if ur wet)

    therefore isV=IR

    V = ?
    I = 1 * 10^-5 A
    R = 500,000 ohms

    therefore V= 0.00001 * 500 = 5 volts

    They are, I learned that from watching "Mythbusters". In the episode they were testing if an iron is dropped into a bathtub will it kill? I remember Adam said that 10 milliamps is enough to kill you.
