Inductance
A coil carrying alternating current produces an alternating flux, which causes to link with same coil and produces an emf in the coil, which opposes the applied emf. This property is known as inductance. The unit for measurement is henry.
Inductive reactance
The opposition or the reactance offered by the property of inductance in the circuit is known as inductive reactance and denoted by the letter XL. The unit for measurement is ohm.
