In an AC circuit, the amount of capacitive reactance ((X_C)) offered by a capacitor is inversely proportional to both capacitance and frequency: [X_C = {1 over {2 pi f C}}] This means an AC signal finds it "easier" to pass through a capacitor (i.e. less ohms of reactance) at higher frequencies than at lower frequencies.

In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effec…
