Question

1. in a low pass rl filter, the output is taken ________.a across the inductor and resistorb across the resistor and inductorc across the inductord across the resistor

Explanation:

In a low - pass RL filter, the inductor blocks high - frequency signals (since inductive reactance \(X_L = 2\pi fL\) increases with frequency \(f\)). At low frequencies, the inductor has low reactance. The output is taken across the inductor. When the frequency is low, most of the input voltage appears across the inductor (because the voltage across the resistor \(V_R=IR\) and \(I=\frac{V}{R + X_L}\), for low \(f\), \(X_L\ll R\) is not the case for the output across the inductor).

Answer:

C. across the inductor
