(N/A) Capacitive reactance is the opposition offered by a capacitor to the flow of an alternating current $(AC)$.
It is denoted by $X_C$.
The formula for capacitive reactance is $X_C = \frac{1}{\omega C} = \frac{1}{2\pi f C}$, where $\omega$ is the angular frequency, $f$ is the frequency of the $AC$ source, and $C$ is the capacitance of the capacitor.
The $SI$ unit of capacitive reactance is the ohm $(\Omega)$.
