Inductive Reactance – Definition
Inductor is basically a coil or choke. When alternating current flows through the inductor then magnetic field creates voltages. If the number of turns increased then induce voltages increased. When the inductor provide resistance or reluctance for the flow of current through it is called Inductive Reactance. The symbol of inductive reactance is XL. The unit of XL is ohm.
