Question

A coil is connected across a non-inductive resistance of 120 ohm
when a 240 V, 50 Hz supply is applied to this circuit the coil
draws a current 5.A and total current is bA . Determine the
power and power factor of the coil as well as the whole
circuit.​

Answer 1

Answer:

In AC circuits, the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. The power factor can get values in the range from 0 to 1. When all the power is reactive power with no real power (usually inductive load) - the power factor is O.
