Reference: AQA
A larger capacitance gives slower oscillations for a given inductance, as a softer spring gives a longer period, with angular frequency ω = 1/√(LC).
The angular frequency of free oscillations is ω = 1/√(LC), justified by treating the inductor as inertial mass and the capacitor as the spring.
