144. . Electricity through the body, I. A person with a body BIO resistance of 10 k2 between his hands accidentally grasps the terminals of a 14 kV power supply. (a) If the internal resist- ance of the power supply is 2000 2, what is the current through the person's body? (b) What is the power dissipated in his body? (c) If the power supply is to be made safe by increas- ing its internal resistance, what should the internal resistance be for the maximum current in the situation just described to be 1.00 mA or less?
