Occasionally, the electric circuit that produces a coordinated pumping of blood from the four chambers of the heart becomes disturbed. Ventricular fibrillation can occur-random muscle contractions that produce little or no blood pumping. To stop the fibrillation, two defibrillator pads are placed on the chest and a large current (about 20 amps) is sent through the heart, restarting its normal rhythmic pattern. The current lasts 5 msms and transfers 380 JJ of electric energy to the body. Find the potential difference between the defibrillator pads.
