In an AC circuit, voltage V = `V_(0)sin omegat` and inductor L is connected across the circuit. Then the instantaneous power will be

If in an A.C. circuit voltage V and current is then the power dissipated in the circuit is …….

For an AC circuit V=15sin omegat and I=20cos omegat the average power consumed in this circuit is

An a.c. source given b V = V_0 sin omegat is connected to a pure indutance L in a circuit. If I_0 is the peak value of the a.c., then the instantaneous power in the inductor is

In an AC circuit, a condenser, a resistor and a pure inductor are connected in series across an alternator (AC generator). If the voltages across them are 20 V, 35 V and 20 V respectively, find the voltage supplied by the alternator.
