Problem 22

Resistance and Current in the Human Finger The interior of the human body has an electrical resistivity of . (a) Estimate the resistance for current owing the length of your index nger. (For this calculation, ignore the much higher resistivity of your skin.) (b)Your muscles will contract when they carry a current greater than 15 mA. What voltage is required to produce this current through your nger?
