power in AC circuit

Derive an experssion for the average power in LCR circuit connected to a.c. supply. Hence define power factor. Show that average power cousumed per cycle in an a.c. circuit conataining an ideal capacitor is zero.

Power in an AC circuit is rated per second at which

For wattless power is an AC circuit, the phase angle between the current and voltagge is

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?

What is the frequency of power in an AC circuit connected to a capacitor. Given f = 50 Hz, V = 220 V

Assertion: Averae power in an AC circuit is given by P= I_(rms)^(2)R Reason: In one full cycle, net power is dissipated only along a resistor.
