Question

In an ac circuit the reactance equal to resistance. The power factor will be

Answer 1

The impedance, (Z) of an AC circuit isequivalent to the resistance calculated in DC circuits, with impedance given in ohms. ... But an AC circuits impedance is not equal to the algebraic sum of the resistive and reactive ohmic values as a pure resistance and pure reactanceare 90o out-of-phase with each other.
