Q. 8. (i) When an ac source is connected to an ideal capacitor show that the average power supplied by the source over a complete cycle is zero. (ii) A lamp is connected in series with a capacitor. Predict your observation when the system is connected first across a dc and then an ac source. What happens in each case if the capacitance of the capacitor is reduced ?
