Physics

A defibrillator delivers a jolt of electrical energy to restarta heart that is either stopped or undergoing ventriculardefibrillation -- a rapid irregular beating. This energy issupplied by a charged capacitor and applied via paddles placed on apatient's body(one on each side of the heart). Consider a 20.7 μFcapacitor charged to 2210 V in a defibrillator and used on apatient. After 9.85×10-2 seconds the voltage across thedefibrillator's paddles drops to 49.6 V.

Find the effective resistance of the body between thedefibrillators paddles. Hint: assume the voltage across the paddlesis the same as the voltage stored on the capacitor.
