Like resistance, reactance is measured in ohms, with positive values indicating inductive reactance and negative indicating capacitive reactance. It is denoted by the symbol ⁠ ⁠.

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.

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 …

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

Together with the resistance, the reactance of a circuit create the impedance by way of analysis of the phasors of the circuit. Without reactance, it is impossible to study alternating current circuits directly.

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.

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.

What is Reactance? The motion of electrons constitutes the current generation in an electrical circuit and any inertia against this motion of electrons constitutes reactance.
