Formule

## 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.

Exemple Résolu

An LC circuit with L = 10 mH and C = 100 μF.

  1. 01f = 1 / (2*pi*sqrt(L*C))
  2. 02f = 1 / (2*pi*sqrt(10e-3 * 100e-6))
  3. 03f = 1 / (2*pi*sqrt(1e-6))
  4. 04f = 1 / (2*pi*0.001)
  5. 05f = 1 / 0.006283 = 159.15 Hz
