Definitions:

Power Factor

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

Phase Angle

The angle or phase difference between two waveforms or signals, often measured in degrees.

Circuit Current

The flow of electric charge in a complete or partial electrical circuit.

Series RC

A circuit configuration where a resistor and a capacitor are connected in a linear sequence, affecting the overall impedance and phase angle.
