LC Circuit Solver
Fill in any two of the three variables — inductance L, capacitance C, or resonant frequency f₀ — and leave the third blank. The tool solves for the missing value. Used for filters, oscillators, RF coil tuning, and matching networks.
Equations & Parameters ▸
\(f_0 = \dfrac{1}{2\pi\sqrt{LC}}\qquad L = \dfrac{1}{4\pi^2 f_0^2\, C}\qquad C = \dfrac{1}{4\pi^2 f_0^2\, L}\)
| L | Inductance. Stores energy in a magnetic field. |
| C | Capacitance. Stores energy in an electric field. |
| f₀ | Resonant frequency. At f₀ the inductive and capacitive reactances are equal and cancel: ωL = 1/(ωC). |
Inputs — fill any two, leave one blank
