suppose we measure the resistance from one hand to the other and find it to be 2 kilo ohms. The measuring electrodes contact a rectangular patch of skin that is .1 m by .01 m on each hand. The thickness of skin is about .002m so the resistance is due to entirely to skin , the total thickness of skin is .004 m
a) What is the resistivity of skin?
b) If the current is to be kept to a safe current of 0.01milli Amps, what voltage must be applied to make the measurement of resistance?
