Inductive and Capacitive Reactance Calculator
In an AC circuit, inductors and capacitors oppose changing current with a frequency dependent resistance called reactance, measured in ohms. This calculator finds it for both. Inductive reactance rises with frequency and equals two pi times frequency times inductance, while capacitive reactance falls with frequency and equals one over two pi times frequency times capacitance. Pick whether you are working with an inductor or a capacitor, enter the component value and the signal frequency, and the tool returns the reactance. This is the key number for designing filters, matching networks, crossovers and tuned circuits, because reactance sets how much an AC signal is blocked or passed at a given frequency. At resonance the inductive and capacitive reactances are equal and cancel out. Enter your values, choosing convenient units, and read the reactance instantly in your browser.
How to use Inductive and Capacitive Reactance Calculator
- Choose whether you are entering an inductor or a capacitor.
- Enter the operating frequency in hertz.
- Enter the inductance or capacitance value with its unit.
- Read the reactance in ohms for that frequency.
Frequently asked questions
How is inductive reactance calculated?
Inductive reactance XL equals 2 pi times frequency times inductance, so it rises with frequency and opposes changing current in an inductor.
How is capacitive reactance different?
Capacitive reactance XC equals 1 divided by 2 pi times frequency times capacitance, so it falls as frequency rises, the opposite trend to an inductor.
What units are the inputs and output?
Enter frequency in hertz and the component in henries or farads, and the reactance is returned in ohms for AC circuit design.
