Question

True power of a capacitor is 1.

(a) True

(b) False

This question was posed to me during an interview for a job.

This interesting question is from Combination of Capacitors in portion Electrostatic Potential and Capacitance of Physics – Class 12

Answer 1

Right choice is (b) False

To elaborate: True power is the actual power consumed by the equipment in order to do useful work in an AC circuit. The true power is measured in watts and signifies the power drawn by the circuit’s resistance to do useful work. But, a pure capacitor does not consume or dissipate any true power. So the true power of a capacitor is zero.
