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 …

In electrical circuits, reactance is the opposition presented to alternating current by inductance and capacitance. [1] It is measured in ohms. [1] Along with resistance, it is one of two …

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.

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

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 …

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 …

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 …

You know that the voltage across a capacitor lags the current because the current must flow to build up the charge, and the voltage is proportional to that charge which is built up on the …

Capacitive reactance (XC) is the opposition to current caused by a capacitor. A capacitor stores energy in an electric field between its plates.

At very high frequencies, the capacitor’s reactance tends to zero—it has a negligible reactance and does not impede the current (it acts like a simple wire).
