Capacitive Reactance Calculator

Formula and Units

Capacitive reactance is opposition to AC current caused by capacitance.

Formula: Xc = 1 / (2 x pi x frequency x capacitance).

Understanding Capacitive Reactance

1. What This Calculator Measures

Capacitive reactance is how much a capacitor opposes alternating current.

2. How the Calculation Works

Frequency is converted to hertz and capacitance to farads. Higher frequency or capacitance lowers reactance.

3. Formula or Rule Used

Xc = 1 / (2 x pi x f x C).
