A 14-µF capacitor and a capacitor of unknown capacitance are both charged to 3.25 kV. After charging, the two capacitors are disconnected from the voltage source. The capacitors are then connected to each other--positive plate to negative plate and negative plate to positive plate. The final voltage across the terminals of the 14-µF capacitor is 1.00 kV. a)What is the capacitance of the second capacitor? b)How much energy is dissipated when the connection was made?
