Question

An a.c. voltage of 5Vr.m.s and frequency 200 Hz is connected in series to a 1100 Ω resistor, 0.012 H inductor and 8μF capacitor. Calculate the reactance of the inductor.

Answer 1

The reactance of the inductor is givem by the following expression:

$$X_L = 2\pi fL$$

where $f = 200 Hz$ the frequency and $L = 0.012H$ is the inductance. Tus, obtain the following numbers:

$$X_L = 2\pi\cdot 200\cdot 0.012 \approx 150.8 \Omega$$

Answer. 150.8 Ohm.
