Question

Power factor of an AC circuit is a measure of power loss in the circuit

Answer 1

Answer:

Explanation:

The power factor of an AC circuit is defined as the ratio of the real power (W) consumed by a circuit to the apparent power (VA) consumed by the same circuit. This therefore gives us: Power Factor = Real Power/Apparent Power, or p.f. = W/VA.

Answer 2

The power factor is equal to real or true power P in Watts divided by apparent power in Volt-ampere.

Explanation:

In ac circuits, power factor is the ratio of real power that is used to do work and the apparent power that is supplied to the circuit.

• Power factor value ranges from 0 to 1.

• When all power is reactive power with no real power, power factor is 0.

• When all power is real power with no reactive power then power factor is 1.
• It is an expression of efficiency of energy.
