The immediate cause of many deaths is ventricular fibrillation, the uncoordinated palpitation of the heart. An electric shock applied to the chest can cause momentary paralysis of the heart muscle, after which the heart sometimes resumes normal beating. One type of defibrillator (pictured below) delivers a strong electrical shock to the chest for a time span of a few milliseconds. The device contains a multi-microfarad capacitor, charged with several thousand volts. Electrodes called paddles are pressed against the chest on both sides of the heart and the capacitor is discharged into the patient's chest. Suppose 300 J energy has to be applied by a 30.0 mF capacitor. What potential difference should this capacitor be charged with?
