An idealinductor consumes no power in an a.c. circuit. Why?

What is wattless current ? Show mathematically that an ideal inductor does not consume any power in an a.c. circuit.

Power In An Ac Circuit

A lamp consumes only 50% of peak power in an a.c. circuit. What is the phase difference between the applied voltage and the circuit current

What do you mean by power in an Ac circuit ?

An electric bulb consumes only 25% of the peak power in an a.c. circuit. What is the phase difference between the circuit and the applied a.c. voltage ?

An ideal inductor when connected in a.c. circuit does not produce heating effect though it reduces the current in the circuit. Explain why ?

Calcualte energy stored in an inductor in an a.c. circuit. Show that average power consumed per cycle in an a.c. circuit containing pure indcutor is zero

STATEMENT-1: AC source is connected across a circuit. Power dissipated in circuit is P . The power is dissipated only across resistance. STATEMENT-2: Inductor and capacitor will not consume any 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.

The minumum and maximum values of power factor in an A.C. circuit are respectively:
