The human body can exhibit a wide range of resistances to current depending on the path of the current, contact area, and sweatiness of the skin. Suppose the resistance across the chest from the left hand to the right hand is 1.20 x 106 n. (a) How much voltage is required to cause possible heart fibrillation in a man, which corresponds to 370 mA of direct current? (b) Why should rubber-soled shoes and rubber gloves be worn when working around electricity?

A person grasps the ends of an electrically conducting copper wire in each hand. The wire has a cross-sectional area of 4.0x106 m² and its surface is not insulated. If the person's hands are wet, the resistance of the possible electrical pathway from one hand, up the arm, across the chest and down into the other hand is about 1 kQ. (a) A current of 10 mA can “freeze" the muscles so the hands are clenched around the wires. Estimate the potential difference between the ends of the wire which would cause this. (b) How much power is dissipated in the person's body if this current flows? (c) The ends of the wire are connected to make a circuit that includes a battery, If the person grasps the wire with hands 0.20 m apart, comment on the resistances of the possible paths of electric current.
