Inductive reactance of 1mH at 100kHz = 628Ω
Worked answer for the reactance of a 1mH inductor at 100kHz, using Xl = 2πfL.
Xl (inductive reactance) 628Ω 1mH inductor · 100kHz
| Frequency (f) | 100kHz |
| Inductance (L) | 1mH |
| Formula | Xl = 2πfL |
| Reactance (Xl) | 628Ω |
Inductive reactance rises as frequency rises — an inductor blocks high frequencies and passes DC (Xl → 0 as f → 0).
