What is the symbol for capacitive reactance?

The symbol for capacitive reactance is represented by "Xc." In the context of AC circuits, capacitive reactance describes how a capacitor opposes the flow of alternating current (AC) due to its capacitance. It is calculated using the formula ( Xc = \frac{1}{2\pi f C} ), where ( f ) is the frequency of the AC signal and ( C ) is the capacitance.

Understanding this symbol is essential for analyzing and designing AC circuits, as capacitive reactance plays a significant role in determining the overall impedance when capacitors are involved. In contrast, other symbols like "R" refer to resistance, "Z" represents impedance, and "Xl" denotes inductive reactance, each relevant to their respective components but not applicable to capacitors specifically. This distinction emphasizes the unique behavior of capacitive reactance in circuit analysis.
