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.
5.15: Changing the Distance Between the Plates of a Capacitor
No headers If you gradually increase the distance between the plates of a capacitor (although always keeping it sufficiently small so that the field is uniform) does the intensity of the field change or does it stay the same? If the former, does it increase or decrease?
