Does the magnitude of the applied voltage influence the capacitive reactance of a circuit?

Capacitive reactance is defined as the opposition that a capacitor offers to the flow of alternating current (AC) due to the capacitance of the component. The formula for capacitive reactance is Xc = 1/(2πfC), where Xc is the capacitive reactance, f is the frequency of the AC signal, and C is the capacitance in farads.

It’s crucial to note that this formula indicates that capacitive reactance is dependent on frequency and capacitance but does not include the applied voltage. Therefore, regardless of the magnitude of applied voltage, the capacitive reactance remains unaffected. This means that changes in voltage will not influence the reactance; it is solely determined by the capacitance value and the frequency of the AC signal.

Understanding these principles clarifies that aspects like voltage level or magnitude do not factor into the capacitive reactance, making it clear why the correct response is that the magnitude of the applied voltage does not influence the capacitive reactance of a circuit.
