A 10.4 ?F capacitor in a heart defibrillator unit is charged fully by a 10000 V power supply. Each capacitor plate is connected to the chest of a patient by wires and flat "paddles," one on either side of the heart. The energy stored in the capacitor is delivered through an RC circuit, where R is the resistance of the body between the two paddles. Data indicate that it takes 73.9 ms for the voltage to drop to 22.0 V . A) Find the time constant. (answer in in ms) B) Determine the resistance, R C) How much time does it take for the capacitor to lose 81 % of its stored energy? (in ms) D) If the paddles are left in place for many time constants, how much energy is delivered to the chest/heart area of the patient? (in joules)
