A large capacitor has a charge + q on one plate and -q on the other. At time t = 0, the capacitor is connected in series to two ammeters and a light bulb. Immediately after the circuit is closed, the ammeter connected to the positive plate of the capacitor reads Ip and the ammeter connected to the negative plate of the capacitor reads IN. (Figure 1) Each ammeter reads positive if current flows through the circuit in a clockwise direction (from...
