Definitions:

Parallel Circuit

An electrical circuit where components are connected across common points or junctions, creating multiple paths for current flow.

Inductive Reactance

The opposition to the change of current flow through an inductor in an AC circuit, caused by the inductor's capacity to store energy in a magnetic field.

Phase

A term that denotes a specific stage in a cycle of a waveform, especially in the context of alternating current (AC) where it indicates the displacement between waveforms.

Parallel Circuit

A type of electrical circuit in which the components are connected alongside each other, forming branches such that each component has the same voltage.
