Consider a defibrillator, acting as a 32 μF capacitor and a 47 kΩ resistor in a series RC circuit. The circuitry in this system applies 5000 V to the RC circuit to charge it.
a) what is the time constant of this circuit?
b) what is the maximum charge on the capacitor?
c) what is the maximum current in the circuit during the charging process?
d) what are the charge and current as functions of time?
e) how much energy is stored in the capacitor when it is fully charged?
