Formula
f = 1 ÷ (2π√(LC))
At ideal resonance, inductive and capacitive reactance magnitudes are equal.
Example
10 mH and 1 µF resonate at approximately 1.592 kHz.
Real-Circuit Behavior
Resistance controls damping, bandwidth, and Q. Component tolerance, parasitics, core loss, ESR, and circuit loading shift and broaden the measured response.
The ideal formula identifies a starting point; precision filters and oscillators require component models and tolerance analysis.
