A capacitor of capacitance C is charged to a potential difference V0. The terminals of the charged capacitor are then connected to those of an uncharged capacitor of capacitance C/2 Compute
(a) The original charge of the system;
(b) The final potential difference across each capacitor;
(c) The final energy of the system;
(d) The decrease in energy when the capacitors are connected.
(e) Where did the “lost” energy go?
