Most of the resistance of the human body comes from the skin, as the interior of the body contains aqueous solutions that are good electrical conductors. For dry skin, the resistance between a person’s hands is typically 510 kiloohm. The skin is on average about 2.00 mm thick. We can model the body between the hands as a cylinder 1.60 m long and 12.0 cm in diameter with the skin wrapped around it. What is the resistivity of the skin?

Let Li represent the original length of the wire, Ai its original cross-sectional area, Ri = ρLi /Ai the original resistance between its ends, and δ = ΔL/Li = (L - Li )/Li the strain resulting from the application of tension.
