Reactance Calculator
Calculate capacitive or inductive reactance from frequency and capacitance or inductance values.
The result will appear here.
How to Use
- Choose capacitive or inductive reactance.
- Enter frequency and component value with units.
- Review reactance and the formula.
Examples
- Calculate Xc for 100nF at 1kHz
- Calculate Xl for 1mH at 10kHz
Calculation and Conversion Notes
Capacitive reactance is calculated as `Xc = 1 / (2πfC)`. Inductive reactance is calculated as `Xl = 2πfL`. Frequency, capacitance, and inductance values are converted according to the selected units before calculation.
