(a) Prove that the current flowing through an ideal inductor connected across a.c. source, lags the voltage in phase by `pi/2`. (b) An inductor of self inductance 100 mH, and a bulb are connected in series with a.c. sources of rms voltage 10 V, 50 z. It is found that effective voltage of the circuit leads the current in phase by `pi/4`. Calculate the inductance of the inductor used and average power dissipated in the circuit, if a current of 1 A flows in the circuit.
