What equation is used to calculate capacitive reactance?

The equation used to calculate capacitive reactance is derived from the relationship between frequency, capacitance, and reactance in AC circuits. The correct formula for capacitive reactance is Xc = 1/(2πfC).

In this formula, Xc represents the capacitive reactance measured in ohms, f is the frequency of the alternating current in hertz, and C is the capacitance in farads. The formula indicates that capacitive reactance decreases with increasing frequency or with increasing capacitance, reflecting the behavior of capacitors in an AC circuit. As frequency increases, the reactance presented by the capacitor becomes less, allowing more current to flow through. This principle is fundamental in understanding how capacitors interact in AC systems.

Other choices do not accurately reflect the relationship and calculations necessary for capacitive reactance.
