The average resistivity of the human body is 5 ohm*m. The conducting path between two hands is approximated as a cylinder with length 1.6m and diameter 0.1 m. Skin resistance is negligible.
a) what is the resistance between the hands?
b) what potential difference between the hands is needed for a lethal current of 100 mA?
c) what power is dissipated in the body from the current in b?
