Reactance is used to compute amplitude and phase changes of sinusoidal alternating current going through a circuit element. Like resistance, reactance is measured in ohms, with positive values …

Apr 17, 2020 · Reactance (also known as electrical reactance) is defined as the opposition to the flow of current from a circuit element due to its inductance and capacitance.

Sep 3, 2025 · Confused about impedance and reactance? Learn the difference, how to calculate them, and how they’re used in real circuits.

Reactance, in electricity, measure of the opposition that a circuit or a part of a circuit presents to electric current insofar as the current is varying or alternating.

Reactance (\ (X\)) is the opposition to an electric current resulting from energy storage and release between certain components and the rest of the circuit, analogous to inertia of a moving object.

Apr 14, 2023 · Reactance is a form of opposition generated by components in an electric circuit when alternating current (AC) passes through it. The term reactance applies only to AC circuits -- both …

The meaning of REACTANCE is the part of the impedance of an alternating-current circuit that is due to capacitance or inductance or both and that is expressed in ohms.

Jun 11, 2023 · Reactance is a key concept in electrical engineering, representing the opposition that inductors and capacitors offer to the flow of alternating current (AC) in a circuit. Reactance is a …

At the higher frequency, its reactance is large and the current is small, consistent with how an inductor impedes rapid change. Thus high frequencies are impeded the most.

Reactance is a measure of the opposition that inductors and capacitors present to alternating current (AC) due to their ability to store energy in magnetic and electric fields, respectively.
