Question

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 12.0 A through the body at 25.0 V for a very short time, usually about 3.00 ms . Part A What power does the defibrillator deliver to the body?

Answer 1

Step-by-step explanation:

Power = work done / time

work done by electricity = Voltage x charge

power = voltage x charge / time

= voltage x current

= 25 x 12

= 300 W .
