We can quickly obtain the capacitive reactance of a capacitor with the capacitive reactance formula: where: X X is the capacitive reactance, in ohms. Alternatively, we can use the angular frequency \omega ω: As you can see, increasing the frequency will decrease the capacitive reactance.
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.
The capacitance of a capacitor determines the amount of charging a capacitor can achieve. The measure of the opposition to alternating current by the capacitor is called Capacitive Reactance. The unit of Capacitive Reactance is Ohms like resistance. The symbol of Capacitive Reactance is XC . Capacitive Reactance Formula is expressed by Where in,
The above equation gives you the reactance of a capacitor. To convert this to the impedance of a capacitor, simply use the formula Z = -jX. Reactance is a more straightforward value; it tells you how much resistance a capacitor will have at a certain frequency. Impedance, however, is needed for comprehensive AC circuit analysis.
Unlike resistance which has a fixed value, for example, 100Ω, 1kΩ, 10kΩ etc, (this is because resistance obeys Ohms Law), Capacitive Reactance varies with the applied frequency so any variation in supply frequency will have a big effect on the capacitor’s, “capacitive reactance” value.
