In the figure, transformer , has two secondary, all three windings having the same number of tums and with polarities as indicated. One secondary is shorted by a 10 Ω resistor R, and the other by a 15 µF capacitor. The switch SW is opened (t = 0) when the capacitor is charged to 5V with the left plate as positive. At t=0+ the voltage and current are
