Formula
The Inductive Reactance Calculator uses the formula:
Inductive reactance = 2 × 3.141592653589793 × Frequency × (Inductance ÷ 1000)
Worked example
For example, with frequency of 50 Hz and inductance of 100 mH, the inductive reactance is 31.416.
| Frequency | 50 Hz |
|---|---|
| Inductance | 100 mH |
| Inductive reactance | 31.416 |

Frequently asked questions
Use XL = 2πfL. At 50 Hz with a 100 mH inductor, the reactance is about 31.4 ohms.
It is the opposition an inductor offers to alternating current, in ohms. It rises with frequency and inductance.
A faster-changing current induces a larger opposing voltage in the inductor, so its reactance grows with frequency.
At zero frequency the reactance is zero, so a steady DC current passes through an ideal inductor with no opposition.
