Definitions:

True Power

The actual power consumed by an electrical device in watts, calculated as the product of voltage, current, and the cosine of the phase angle between them.

Applied Voltage

The external voltage applied across a component or circuit, driving current through it according to Ohm's Law.

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.
