Definitions:

Inductive Reactance

The opposition offered by an inductor to alternating current, depending on the frequency of the current and the inductance of the coil.

Inductive Reactance

The opposition to the change of electric current in an inductor, measured in ohms.

Impedance

A measure of the opposition that a circuit presents to the passage of alternating current, expressed in ohms and combining resistive and reactive elements.

Resistance

The property of a material or component that opposes the flow of electric current, measured in ohms (Ω).
