Consider capacitors C1, C2, and C3, which are connected in series in a closed loop. A switch is placed between C1 and C2. With the switch open, C1is charged to 12.0 volts by a battery. The battery is then disconnected and the switch is closed
Determine the final charge on each capacitor, and the potential difference across each, given that C1 = 2.00 ?F, and C2 = C3 = 3.00 ?F.
