Nov 1, 2025 · Capacitive Reactance, (X C) is the reactance of a capacitor which limits the flow of alternating current (AC) through it. Capacitive reactance can be thought of as a variable resistance, …

Use the capacitive reactance calculator whenever you want to find a capacitor's reactance in an AC circuit.

Capacitive reactance is an opposition to the change of voltage across an element. Capacitive reactance is inversely proportional to the signal frequency (or angular frequency ) and the capacitance ⁠ ⁠.

The capacitive reactance is a measure of how a capacitor restricts the flow of alternating current, although similar to resistance, it is not the same.

Jul 23, 2025 · Capacitive reactance is the opposition presented by a capacitor to the flow of alternating current (AC) in a circuit. Unlike resistance, which remains constant regardless of frequency, …

Although a capacitor is basically an open circuit, there is an rms current in a circuit with an AC voltage applied to a capacitor. This is because the voltage is continually reversing, charging and discharging …

The ratio of effective voltage across the capacitor to the effective current is called the capacitive reactance and represents the opposition to current flow. Its symbol is XC and is measured in ohms.

Calculating Capacitive Reactance The quantitative relationship for capacitive reactance is represented by the formula: XC = 1/(2πfC). This equation establishes the precise mathematical dependency of …

Oct 7, 2025 · One opposing force is capacitive reactance, a property of components called capacitors. In an AC circuit, a capacitor continuously charges and discharges, and capacitive reactance is the …

Nov 9, 2022 · Capacitive reactance, measured in ohms (Ω), is the resistance-like property that opposes the flow of alternating current (AC) through a capacitor in an electrical circuit.
