Definition :

The apparent resistance in an electric circuit to the flow of an alternating current analogous to the actual electrical resistance to a direct current being the ratio of electromotive force to the current It is equal to R2 X2 where R ohmic resistance X reactance For an inductive circuit X 2pifL where f frequency and L self inductance for a circuit with capacity X 1 divide 2pifC where C capacity
