The relatively high resistivity of dry skin, about 1 x 10^6 ohms - m, can safely limit the flow of current into deeper tissues of the body. Suppose an electrical worker places his palm on an instrument whose metal case is accidently connected to a high voltage. The skin of the palm is about 1.5mm thick. Assume the area of skin on the worker's palm that would contact a flat panel is 1.0×10^?2 m^2 , then calculate the approximate resistance of the skin of the palm.
