Definitions:

Power Factor

A measure of how effectively electrical power is converted into useful work output, expressed as the ratio of real power flowing to the load to the apparent power in the circuit.

RLC Series Circuit

An electrical circuit consisting of a resistor (R), inductor (L), and capacitor (C) connected in series, used to filter or resonate at certain frequencies.

Capacitance

Refers to the amount of electric charge that a capacitor can hold, measured in Farads, at a given voltage.

Reactive Power

The component of electrical power that does not result in useful work, measured in VARs (volt-amps reactive), and is generated by reactive components like capacitors and inductors.
