Definitions:

Apparent Power

The measure of the total power in an electrical circuit, represented as the product of voltage and current without taking phase differences into account.

Series RC

An electrical circuit configuration where a resistor (R) and a capacitor (C) are connected in series with each other.

Power Factor

The ratio of real power flowing to the load to the apparent power in the circuit, indicating the efficiency with which electrical power is converted into useful work output.

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.
