Frequency (MHz)1.5915 MHz

Resonant Frequency vs Inductance

LC Resonant Frequency

f = 1 / (2 x pi x sqrt(L x C))

At resonance, inductive and capacitive reactances are equal and cancel, allowing maximum energy transfer.

Example Calculation

100 uH and 100 pF.

  1. 01L = 100 uH = 0.0001 H
  2. 02C = 100 pF = 1e-10 F
  3. 03f = 1 / (2pi x sqrt(0.0001 x 1e-10))
  4. 04f = 1 / (2pi x sqrt(1e-14)) = 1 / (2pi x 1e-7)
  5. 05f = 1,591,549 Hz = 1.5915 MHz
