Frequently asked questions
Use f = 1 ÷ (2π√(LC)). With 1 mH and 1 µF, the resonant frequency is about 5,033 Hz.
It is the frequency where inductive and capacitive reactances cancel, giving maximum response.
Lower inductance or capacitance to raise it; increase either to lower it.
Radio tuning, filters and oscillators all rely on LC resonance.
