When the switch is in position a below, the battery charges the positive parallel plate of the capacitor to Q = 900 µC. The switch then swings to position b, the charge Q flows through the resistor R, and the capacitor’s stored energy U is turned into heat energy. Assume the capacitor has capacitance C = 8.00 µF. Use conservation of energy to find the amount of heat (in Joules) produced during the capacitor’s discharge.
