In an LC circuit, if we increase the capacitor's capacitance (while keeping everything else the same), the circuit's oscillation frequency will
A) increase.
B) decrease.
C) remain the same.
D) One needs more information to answer.

Question

Quizplus · Accepted Answer

The oscillation frequency of an LC circuit is given by $f = \frac{1}{2\pi\sqrt{LC}}$, where $L$ is the inductance and $C$ is the capacitance. Increasing the capacitance ($C$) will increase the denominator, thus decreasing the frequency ($f$).
