Since a capacitor reacts when connected to ac, as shown by these three factors, it is said to have the property of reactance — called capacitive reactance. The symbol is X C, and the unit is the ohm: [X_{C}=frac{1}{2pi fC}] Where. X C = capacitive reactance (Ω) f = frequency (Hz) C = capacitance (Farad)

Capacitive reactance: Basics and applications | Electronics360
As the capacitor charges and discharges, the electric current that flows through it is restricted by the internal impedance of the capacitor. This internal impedance is the capacitive reactance of the capacitor. Capacitive reactance is measured in Ohms (Ω) and can be calculated using: Where: f = frequency (Hz) C = capacitance (F)

We need some extra energy over capacitive reactance to charge up a capacitor in the circuit. This value is inversely proportional to the capacitance value and the frequency of supply voltage. Xc∝ 1/c and Xc∝ 1/f. The equation for capacitive reactance and parameters which influences them are discussed in below.
Reactance is also expressed in ohms. There are two kinds — capacitive and inductive. The im- pedance of a capacitor or an inductor changes as the frequency of operation changes. The part of the impedance that is frequency dependent is called "capacitive reactance" in capacitors and '' ''inductive reactance" in inductors.
The quantity (X_C) is known as the capacitive reactance of the capacitor, or the opposition of a capacitor to a change in current. It depends inversely on the frequency of the ac source—high frequency leads to low capacitive reactance. Figure (PageIndex{4}): (a) A capacitor connected across an ac generator.
