Power factor can often be improved by the use of capacitor of appropriate capacitance in the circuit.

Can a capacitor of suitable capacitance replace a choke coil in an ac circuit?

A capacitor, resistor of 5 ohm and an inductor of 50 mH are in series with an a.c. source marked 100V-50hz. It is found that voltage is in phase with the current. Calculate the capacitance of the capacitor and the impedance of the circuit.

On what factors the capacitance of a capacitor depends?

Average power dissipated in pure capacitor in a.c. circuit is:
