Answer:

the inductive reactance of the coil is 1335.35 Ω

Step-by-step explanation:

Given;

inductance of the coil, L = 250 mH = 0.25 H

effective current through the coil, I = 5 mA

frequency of the coil, f = 850 Hz

The inductive reactance of the coil is calculated as;


X_l = \omega L = 2\pi f L\\\\X_l = 2\pi * 850 * 0.25\\\\X_l = 1335.35 \ ohms

Therefore, the inductive reactance of the coil is 1335.35 Ω
