Definitions:

Apparent Power

The total power in an AC circuit, represented as the product of voltage and current without factoring in the phase angle, measured in Volt-Amperes (VA).

Applied Voltage

The voltage that is applied across a component or circuit, initiating the flow of current.

Inductive VARs

In power systems, inductive VARs (Volt-Ampere Reactive) are reactive power components generated by inductive loads, contributing to the overall power factor but not to the actual work performed.

Power Factor

A dimensionless measure of how effectively electrical power is converted into useful work output, particularly the ratio of real power to apparent power in a circuit.
