The formula 1/(2πfC) is associated with the calculation of which of the following?

The formula 1/(2πfC) is used to calculate capacitive reactance, denoted as Xc, in an AC circuit. This relationship shows how the reactance of a capacitor is inversely proportional to both the frequency (f) of the alternating current and the capacitance (C) of the capacitor.

When frequency increases or capacitance decreases, the capacitive reactance will lower, meaning that the capacitor allows more AC current to pass through. Conversely, as frequency decreases or capacitance increases, the capacitive reactance rises, restricting the flow of AC current. Thus, this formula directly relates to the behavior of capacitors in AC circuits, making it crucial for understanding how capacitors interact with voltage and current at different frequencies.

Inductive reactance, impedance, and voltage drop pertain to different aspects of circuit behavior and are calculated using different formulas, which do not match the context provided by 1/(2πfC).
