Inductor & Reactance Calculator
Calculate inductive reactance (XL = 2πfL), LC resonant frequency, and time constants for inductor circuits.
How It Works
Calculate inductive reactance (XL = 2πfL), LC resonant frequency, and time constants for inductor circuits. Enter your values above and click Calculate to get instant results.
Formula
XL = 2πfL | f_resonant = 1 / (2π√LC)
Quick Examples
- 10mH at 1kHz → XL = 62.8Ω
- 10mH + 10µF → resonant at 503Hz
Frequently Asked Questions
What is inductive reactance?
Inductive reactance (XL) is the opposition an inductor presents to AC current. It increases with frequency: XL = 2πfL. Unlike resistance, it does not dissipate power.
What is LC resonance?
An LC circuit resonates when inductive reactance equals capacitive reactance. At resonance, impedance is minimal (series) or maximum (parallel), useful in filters and oscillators.
