5.13: Sharing a Charge Between Two Capacitors
The energy stored in the two capacitors is less than the energy that was originally stored in (text{C}_1). What has happened to the lost energy? A perfectly reasonable and not incorrect answer is that it has been dissipated as heat in the connecting wires as current flowed from one capacitor to the other.
