Biomedical Application. The parts of the body that are most sensitive to electric currents are the brain, the chest muscles and the nerve centers that controls respiration and the heart. A current of 1mA passing through the body will barely be noticeable, but a current of 80mA will usually be fatal unless it is immediately stopped. In most situations, the amount of current that will flow into the body will depend on the condition of the skin at contact locations. Dry skin will have a high resistance but damp or wet skin will have low resistance. Why?
