\[X_L=2\pi fL\]
Variables
Xlinductive reactance (ohm)
fAC frequency (Hz)
Linductance (H)
Description
What is this formula?
This formula calculates the inductive reactance of an inductor in an alternating current circuit.
When to use it
Use it when determining how strongly an inductor opposes alternating current at a given frequency.
Example
Data:
f = 60 Hz
L = 0.25 H
Formula:
Xl = 2*pi*f*L
Substitution:
Xl = 2*pi*60*0.25
Result:
Xl = 94.2 ohm
Applications
AC circuit analysis, transformers, filters, power electronics, impedance calculations, and electrical engineering.
