A cardiac defibrillator is a device used to shock the heart with electrical energy to bring the heart back to beating with its normal rhythm. A typical defibrillator charged to 5000 V delivers 300 J of electrical energy when used on a patient. How much charge is delivered to the patient in this process? Give your answer as a number expressed in coulombs, but do not enter units.
