Definitions:

Inductive Reactance

The opposition that an inductor presents to alternating current, due to the inductor's inductance, measured in ohms.

Power (P)

The rate at which electrical energy is transferred by an electric circuit, usually measured in watts (W).

Parallel Circuit

An electrical circuit in which components are connected across common points or junctions, allowing multiple paths for the current.

Resistor Current

The current flowing through a resistor, determined by the voltage across the resistor and its resistance according to Ohm's law.
