I attach a voltage source to a 45 mF capacitor until it is fully charged. I then take the voltage source away and discharge the capacitor through a 120 Ω resistor in a basic RC circuit. If the initial current through the circuit during discharge is 0.5 A, what voltage did I apply to the capacitor to charge it?
