A heart defibrillator has a bank of eight identical 8.80 μF capacitors in parallel. The eight capacitors each have a dielectric thickness of 0.090 mm, a dielectric constant of 110 and a dielectric strength of 55.0 x 106 V/m. The capacitors are charged to 80% of their maximum working voltage before being discharged across the patient’s chest in a very short (10.0 ms) burst. Calculate the average power dissipated across the patient’s chest during the discharge. This power may appear very large (it is) but it is only for a very short time – just long enough to get your heart to start pumping.
