Definitions:

Parallel Circuit

An electrical circuit configuration where multiple paths are available for current flow, resulting in each component having the same voltage applied.

Inductor Value

The measure of an inductor's ability to store energy in a magnetic field, usually identified by its inductance, measured in henries (H).

Inductive Current

Current that is induced by a changing magnetic field, often described in terms of electromagnetic induction or the inductance property in a circuit.

Inductive Reactance

The opposition to the change of current flow due to inductance in an AC circuit, measured in Ohms.
