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

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.

If the power factor in an AC circuit changes from (1)/(3) to (1)/(9) then by what percent reactance will change (approximately), If resistance remains constant?
