Question
Besides capacitance, which quantity determines the capacitive reactance of an ideal linear capacitor in sinusoidal steady state?
The correct answer is
Frequency
\(X_C=\dfrac1{2\pi f C}\). Thus capacitance and frequency determine the reactance of an ideal linear capacitor; it is independent of signal amplitude.
