Reactive Power

The portion of electricity that does not result in useful work, typically present in AC circuits, and needed for maintaining the voltage levels necessary for active power transfer.

Apparent Power

The total power in an AC circuit, expressed in Volt-Amperes (VA), that combines both reactive and real power components.

Total Voltage

The voltage applied to the circuit.
