How it works
Fill in the 2 fields above and LC Resonant Frequency Calculator calculates the result instantly, recalculating as you change any value. It applies the formula f = 1/(2π√(LC)). The math runs locally in your browser — nothing is sent to a server.
Formula
f = 1/(2π√(LC))Examples
- Inductance 10 mH, Capacitance 100 µF → Resonant frequency: 159.1549 Hz
