Capacitance and frequency have an inverse relationship in certain contexts, particularly in resonant circuits. When a circuit includes both inductors and capacitors, the resonant frequency can be calculated using the formula 1/(2π√(L*C)), where L is inductance in henrys and C is capacitance in farads. This indicates that as capacitance increases, the resonant frequency decreases, and vice versa. Confusion arises because capacitance can affect frequency differently depending on the circuit configuration. Understanding this relationship is crucial for analyzing circuit behavior.
