Inductive Reactance (XL) vs Inductance
Formule
## Inductive Reactance **XL = 2 x pi x f x L** Reactance increases with frequency: inductors pass DC and block high frequencies (opposite of capacitors).
Exemple Résolu
10 mH inductor at 1 kHz.
- 01L = 10 mH = 0.01 H
- 02XL = 2 x pi x 1000 x 0.01 = 62.83 ohms
Questions Fréquentes
Why does reactance increase with frequency?
Faster-changing current induces a larger back-EMF opposing the current, increasing effective impedance.
Inductor vs capacitor reactance?
Inductor reactance rises with frequency; capacitor reactance falls. They are complementary.
What about DC resistance?
Real inductors have wire resistance (DCR) that adds to the impedance.
