Enter the total inductance and the frequency into the calculator. The calculator evaluates and displays the inductor impedance.

Inductor Impedance Formula

The following formula is used to calculate an inductor impedance.

XL = 2 * pi * f * L
  • Where XL is the inductor impedance (ohms)
  • f is the frequency (Hz)
  • L is the inductance (henries)

To calculate the inductor impedance, multiply the frequency by the inductance, then multiply by 2 times pi.

Inductor Impedance Definition

The impedance of an inductor is a measure of the inductor’s ability to resist a signal passing through it. Note that this is different from voltage. This has to do with signals and frequencies.

Inductor Impedance Example

How to calculate an inductor impedance?

  1. First, determine the frequency.

    Measure the frequency in hertz.

  2. Next, determine the inductance.

    Measure the inductance of the inductor.

  3. Finally, calculate the impedance.

    Calculate the impedance of the inductor using the formula above.
