Reactance & resonance

Inductive and capacitive reactance at a frequency, their net reactance, and the series resonant frequency.

Leave a field blank to skip its result.

Calculated in this browser. Nothing is sent anywhere.

Ideal L and C only — ESR, parasitics and tolerance are not modeled.

How to use

  1. Enter the frequency.
  2. Enter inductance and/or capacitance with units.
  3. Read XL, XC, net reactance, and the resonant frequency.

What it supports

XL = 2πfL, XC = 1/(2πfC), resonance 1/(2π√LC). Frequency 0.01 Hz–1 THz, L 1 pH–1 kH, C 1 fF–1 kF. Ideal components only — ESR, parasitics, and tolerance are not modeled.
