Definitions:

Reactive Power

The component of electrical power that does not result in useful work, measured in VARs (volt-amps reactive), and is generated by reactive components like capacitors and inductors.

Inductive Reactance

A measure of the opposition that an inductor presents to alternating current, due to the magnetic field created by the current.

Capacitive Reactance

The resistance that a capacitor offers to alternating current, depending on the frequency of the current and the capacitor value, measured in ohms.

AC Circuit

A circuit in which the current changes direction periodically, powered by an alternating voltage source.
