The current required to stimulate the heart during ventricular fibrillation is about 110mA (1000mA = 1A). Assuming that a conducting gel is used in conjunction with a defibrillator to overcome skin resistance, so that the main resistance of the body to an applied voltage is solely due to the internal resistance of the body, which is roughly around 300 ohms, what voltage is required for defibrillation? (Note, the actual value used is 10-100 times this since the skin's large resistance cannot necessarily be neglected.)
