  1. Electrical reactance - Wikipedia

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

  2. Electrical Reactance: What is it? (Inductive & Capacitive)

    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.

  3. Impedance vs Reactance – Simple Guide with Formulas & Uses

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

  4. What is reactance? – TechTarget Definition

    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 …

  5. Reactance | Electronics, Psychology & Communication | Britannica

    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.

  6. Resistance, Reactance, and Impedance | Basic Alternating Current …

    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.

  7. What is reactance? – Electricity – Magnetism

    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.

  8. Reactance Definition - Intro to Electrical Engineering Key Term | Fiveable

    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.

  9. 23.2: Reactance, Inductive and Capacitive - Physics LibreTexts

    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.

  10. What is Reactance? - BYJU'S

    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 …
