LC Resonance Calculator

Calculate the resonant frequency of an LC circuit. Enter inductance and capacitance to find frequency, period, and wavelength — or solve for any unknown.

Calculate Resonance

Enter inductance (L) and capacitance (C) to compute the resonant frequency and related quantities.

1 mH = 0.001 H, 1 μH = 0.000001 H  |  1 μF = 0.000001 F, 1 nF = 0.000000001 F

Formula

f = 1 / (2π√(LC))

Resonant Frequency (f): 5,032.9212104487 Hz

Angular Frequency (ω): 31,622.7766016838 rad/s

Period (T): 0.0001986918 s

Impedance at Resonance (Z): 0 Ω (ideal)

Wavelength (λ): 59,607.5295947766 m

Key formulas: f = 1/(2π√LC)  |  ω = 1/√LC  |  T = 1/f  |  λ = c/f

Solve for Unknown

Enter any two of frequency (f), inductance (L), or capacitance (C) — leave the third blank to solve for it.
