LC resonance calculator

Calculate resonance with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use resonance to compare changes to your inputs. The method and limits below explain the scope.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Calculation steps and notation

sqrt(x) is the non-negative square root of x.

π is the circle constant, approximately 3.141592653589793.

Assumptions & limits

Assumptions & limits

  • Ideal LC resonance ignores resistance and parasitic effects.
