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” …

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.

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.

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.

Inductive and capacitive reactance have opposite effects in relation to frequency. Inductive reactance rises with an increase in frequency, and capacitive reactance falls. Both are similar …

Write the formula for determining total reactance (X); compute total reactance (X) in a series circuit; and indicate whether the total reactance is capacitive or inductive.

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.
