Definitions:

Reactive Power

The component of electrical power that does not perform any work, typified by its presence in AC circuits and measured in Volt-Amps Reactive (VAR).

Inductive Reactance

The opposition that inductance offers to alternating current, dependent on the frequency of the current.

Resistance

A measurement of the opposition to the flow of electric current, causing electrical energy to be converted into heat.

Apparent Power

The product of the current and voltage in an AC circuit, measured in volt-amperes, which may differ from the actual power due to phase differences.
