Definitions:

Inductive Reactance

The opposition that an inductor presents to alternating current, due to the inductor's tendency to resist changes in current flow, measured in Ohms (Ω).

Parallel Circuit

A type of electrical circuit in which multiple components are connected across the same voltage source, allowing current to split and flow through multiple paths.

Supply Voltage

The electrical potential difference provided by a power source to operate electrical circuits, devices, or equipment, essential for the functioning of electronic systems.

Inductor Current

A measure of the flow of electric charge through an inductor, influenced by the inductor's properties and the circuit it is part of.
