Customer ServiceCapacitive reactance, denoted by 𝑋𝐶 XC, is a measure of a capacitor''s opposition to alternating current (AC). Unlike resistance in direct current (DC) circuits, which dissipates energy, capacitive reactance results from the capacitor''s ability to store and release energy, leading to a phase shift between voltage and current.

Customer ServiceCapacitive reactance is the opposition offered by a capacitor to the flow of electric current through it. The capacitive reactance depends on the frequency. We use capacitors in AC and DC circuits. The behavior of the capacitor is different for AC and DC. Why? it is because DC frequency is zero and AC frequency has some definite value.

Customer ServiceCapacitive reactance is an opposition to the change of voltage across an element. Capacitive reactance is inversely proportional to the signal frequency (or angular frequency ) and the capacitance . There are two choices in the literature for defining reactance for a capacitor.
The two factors that determine the capacitive reactance of a capacitor are: Frequency (f): The higher the frequency of the AC signal, the lower the capacitive reactance. This is because at higher frequencies, the capacitor charges and discharges more rapidly, reducing its opposition to current flow.
Capacitive reactance is the opposition presented by a capacitor to the flow of alternating current (AC) in a circuit. Unlike resistance, which remains constant regardless of frequency, capacitive reactance varies with the frequency of the AC signal. It is denoted by the symbol XC and is measured in ohms (Ω).
A capacitor with a sinusoidal voltage of frequency f across it will have a sinusoidal current flowing through it. The ratio of the voltage to the current is known as the ‘reactance’ of the capacitor at frequency f. The situation is analogous to that with a resistor, and the unit of reactance is again ohms. And Ohm's Law again applies:
We can calculate the reactance of a capacitor at any particular frequency using the expression: where C is the capacitance in farads and f is the frequency. We can see from this that the magnitude of the reactance of a capacitor decreases proportionally with frequency. But hold on! Capacitors are more than ‘frequency-dependent resistors’.
As with inductors, the reactance of a capacitor is expressed in ohms and symbolized by the letter X (or X C to be more specific).
