A defibrillator consists of a 15-μF capacitor that is charged to 9.0kV.?

Question

If the capacitor is discharged in 2.0 ms, how much charge passes through the body tissues?

What is the average power delivered to the tissues?

Answer 1

P=E/t
P -power
E - energy
t - time that energy flows
also
E=.5CV^2
C- capacitance
V- voltage across the capacitor
we have
P=.5CV^2/t
P=CV^2/(2t)=
P=15.0 e-6 (9.o e+3)^2/(2 x 2.0 e-3)=
P=303,750 Watts
Actually this is enough power to cook the patient.
The energy storage is about 200Joules fro atypical unit at this discharge rate it would deliver 100,000 Watts of juice.
