Question

4. A coil having a resistance of 20 ohm and inductance of 0.2 H is connected in series with another coil of resistance of
30 ohm and inductance of 0.04 H to a 230V, 50 Hz supply. Determine (a) voltage across each coil. (b) power dissipated in
each coil (c) power factor of 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 0.
