The average power delivered to a series AC circuit is given by (symbols have their usual meaning):

Power delivered by an ac source of angular frequency Omega_(0) to an LCR series circuit is maximum when .

The average power dissipated in A.C. circuit containing resistance, inductance and capacitance depends upon

Find power in entire circuit where internal resistance is 0.6 ohm.

The power factor of a CR circuit is (1)/(sqrt(2)) . If the frequency of ac signal is halved, then the power factor of the circuit becomes

In an L-C-R ereis circuit R=150Omega, L=0.0750 H and C=0.0180muF . The source has voltage amplitude V=150V and a frequencey equal to the resonacne frequency of the circuit. (a) What is the power factor ? (b) What is the average power delivered by the source? (c) The capacitor is replaced by one with C=0.0360muF and the source frequency is adjusted to the new resonance value. Then, what is the average power delivered by the source?

The average power dissipated in AC circuit is 2W. If a current flowing throuh a circuit is 2A, impedance is 1Omega , then what is the power factor of the circuit?
