Suppose that each of a person's hands makes contact with a different conductor over a surface area of 11.0 cm2. We measure the hand-to-hand resistance of the body by connecting the conductors to an ohmmeter that reads 1.09 104 %u03A9 when the hands are dry. We know that internal body resistance is only about 600 %u03A9.
(a) Find the resistance across a 11.0 cm2 section of the skin.
(b) Find the resistivity of the skin, assuming it is 1.01 mm thick.
(c) Suppose the area of contact of each hand with a conductor is reduced to 1.10 cm2. Find the resistance between the hands.
