LC Circuit Resonant Frequency Calculator

LC Circuit Resonant Frequency is intended for the specific electrical task described by its name. Enter inductance henries, capacitance farads to calculate a result expressed in Hz. The formula works entirely in your browser and needs no account or external API. Ideal LC circuit, excluding resistance and parasitic components. This estimate is useful for comparing scenarios when the supplied measurements follow the stated assumptions.

How to use this calculator

  1. Measure inductance henries in the units indicated on the input label.
  2. Enter Capacitance farads.
  3. Read the Hz result, then compare alternative inputs to evaluate your own situation.

LC Circuit Resonant Frequency formula

1/(2*Math.PI*Math.sqrt(inductance*capacitance)) (Hz).

  • The expression 1/(2*Math.PI*Math.sqrt(inductance*capacitance)) combines Inductance henries, Capacitance farads. Follow the units on each input: the answer is expressed in Hz.
  • Ideal LC circuit, excluding resistance and parasitic components.

Worked examples

Worked example: LC Circuit Resonant Frequency

Use these sample measurements: Inductance henries = 0.1, Capacitance farads = 0.00001.

Compute 1/(2*Math.PI*Math.sqrt(inductance*capacitance)).

Using the example inputs, the result is 159.1549 Hz. Use this value to verify the formula before changing the measurements.

Understanding the result

Interpret the output as Hz; it is not a measurement taken directly from a physical system.

Ideal LC circuit, excluding resistance and parasitic components.

Important notes

Ideal LC circuit, excluding resistance and parasitic components.

Review the input units, any required legal or engineering rules, and unusual edge cases before acting on this estimate.
