Question

A defibrillator used to restore normal heart rhythm consistsessentially of a capacitor, a high voltage supply used to chargethe capacitor, and a pair of paddles (electrodes) placed on thepatient's chest. The charged capacitor is discharged in a shorttime through the patient's body. (Thisis an oversimplified version of the real instrument. In a realinstrument not all of the energy stored in the capacitor isdelivered to the patient's body.) Suppose theresistance of the body is 3000 . A 10 F capacitor is connected to a 10000 V supply.

Explanation / Answer

given that R = 3000 v = 10000v C = 10F energy stored in the capacitor = 1/2 *cv2 plug in values = -------J time constant = = RC = ------s
