LC Resonant Frequency Calculator — Formula
## LC Resonant Frequency
An LC circuit oscillates at a natural frequency determined by the inductance and capacitance.
### Formula
**f = 1 / (2*pi*sqrt(L*C))**
At resonance, the inductive and capacitive reactances are equal and cancel, leaving only resistance to limit current.

Exemplo Resolvido
An LC circuit with L = 10 mH and C = 100 μF.
- f = 1 / (2*pi*sqrt(L*C))
- f = 1 / (2*pi*sqrt(10e-3 * 100e-6))
- f = 1 / (2*pi*sqrt(1e-6))
- f = 1 / (2*pi*0.001)
- f = 1 / 0.006283 = 159.15 Hz
