Academics

A heart defibrillator is used to enable the heart to start beating if it has stopped. This is done by passing a large current of 12 A through the body at 24 V for a very short time, usually about 2.7 ms .

Part A. What power does the defibrillator deliver to the body? Express your answer using two significant figures.

Part B. How much energy is transferred? Express your answer using two significant figures.
