The resistance of a capacitor to the flow of AC current is measured as capacitive reactance. We measure it in ohms (), which is represented by the symbol ‘Xc’. Capacitive Reactance Formula: The magnitude of capacitive reactance depends on the frequency (f) of the AC signal and the capacitance (C) of the capacitor.
The formula to calculate this changing resistance (reactance) is given as below: X C = 1 / 2π f C We are able to determine the resistance that a capacitor provides to AC (alternating current) at a certain frequency.
This is the capacitive reactance calculator – a great tool that helps you estimate the so-called resistance of a capacitor in an electric circuit. You can find the capacitive reactance formula in the text below, and we explain why the reactance occurs for alternating current but not direct current.
Capacitors have a special way of opposing alternating current (AC) which is called capacitive reactance. This is like an internal resistance in the capacitor which changes based on the frequency of the electricity flowing through it.
The formula for capacitive reactance (XC) of a capacitor is: X C = 1 / (2 * π * f * C) We are given the values for XC and f, and want to solve for C. Let’s rearrange the formula to isolate C: C = 1 / (2 * π * f * XC)
Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance.
