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.

When the alternating current goes through a pure reactance, a voltage drop is produced that is 90° out of phase with the current. Reactance is mathematically symbolized by the letter “X” and is measured …

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

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 …

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, 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.

Learn what reactance is and how inductive (XL) and capacitive (XC) reactance affect AC impedance, power factor, and voltage drop in electrical circuits.

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. It is primarily generated due to …

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.
