What Is Capacitive Reactance?
Capacitive reactance is the opposition that a capacitor presents to alternating current. It decreases as the frequency and capacitance increase.
How is it calculated?
How Is It Calculated?
X_C = 1 ÷ (2π × f × C)
- Enter the frequency (Hz) and the capacitance (farad).
Unit: ohm (Ω).
Frequently Asked Questions
How does a capacitor behave at high frequency?
As the frequency increases, the capacitive reactance decreases; the capacitor passes high frequencies more easily.
