Definitions:

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.

Capacitive VARs

Reactive power measured in Volt-Ampere Reactive (VAR) generated by capacitive loads, which can be used for power factor correction in electrical systems.
