Calculate the reactance

Capacitive reactance (symbol

AC (alternating current). Like resistance it is measured in ohms, but

reactance is more complex than resistance because its value depends on the

frequency (

as on the capacitance,

Capacitive reactance,

where:

The reactance

For steady DC which is zero frequency,

hence the rule that capacitors pass AC but block DC.

For example a 1 µF capacitor has a reactance of 3.2 kΩ for a 50 Hz signal, but

when the frequency is higher at 10 kHz its reactance is only 16 Ω.

**Capacitance*** C***, frequency *** f***, and capacitive reactance ***X*_{C}

Enter the values for capacitance and frequency, then press "calculate".

Capacitive reactance is an opposition to the change of voltage across an
element. Capacitive reactance X_{C} is inversely proportional to the signal
frequency f (or angular frequency ω) and the capacitance C. |
