Question

A person notices a mild shock if the current along a paththrough the thumb and index finger exceeds
80 uA. Compare the maximum possible voltage without shock acrossthe thumb and index finger with a dry-skin resistance of 4.0 X10e5 and a wet-skin resistance of 2 000 . A person notices a mild shock if the current along a paththrough the thumb and index finger exceeds
80 uA. Compare the maximum possible voltage without shock acrossthe thumb and index finger with a dry-skin resistance of 4.0 X10e5 and a wet-skin resistance of 2 000 .

Explanation / Answer

voltage = IR . dry skin:     voltage = 80 x10-6 * 4.0 x 105   =    32Volts . wet skin:    voltage = 80 x10-6 * 2000   =     0.160Volts
