`(i)` When an `AC` source is connected to an ideal inductor show that the average power supplied by the source ever a complete cycle is zero.
`(ii)` A lamp is connected in series with an inductor and an `AC` source. What happens to the brightness of the lamp when the key is plugged in and an iron rod is inserted the indcutor ? Explain.

When an AC source is connected to an ideal inductor show that the average power supplied by the source over a complete cycle is zero.

Answer the following: (i) When an AC source is connected to an ideal inductor show that the average power supplied by the source every complete cycle is zero. (ii) A lamp is connected in series with an inductor and an AC source. What happens to the brightness of the lamp when the key is plugged in and an iron rod is inserted in the inducutor ? Explain.

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.

Show that the average power supplied to an ideal capacitor by the source over a complete cycle is zero.

A lamp is connected is series with a a capacitor and an AC source, what happens if the capacity of the capacitor is reduced ?

(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 an ac source. What happence in each case if the capacitance of the capacitor is reduced ?
