Definitions:

Power Factor

A dimensionless number between -1 and 1 that represents the phase difference between the voltage and current in an alternating current (AC) electrical circuit.

Parallel Circuit

A circuit configuration where components are connected across each other's points, allowing multiple paths for the current to flow.

Inductive Reactance

A property of an electrical circuit element that opposes the change in current flow, especially notable in coils or inductors, affected by frequency and inductance.

Total Current

The overall flow of electric charge through a circuit, determined by the sum of all individual current paths within the circuit.
