Question

In the circuit shown in Figure, for output voltage $V_{AB}$ acts as

• A. band-pass filter
• B. low-pass filter
• C. high-pass filter
• D. band reject filter

Answer 1

The correct option is B low-pass filter

Impedance of Inductor is given by $X=j\omega L$

where $\omega$ is frequency and $L$ is inducatance.

For High frequency $X\to \infty$ and It act as open Circuit.

For Low frequency $X\to 0$ and It act as conducting wire.

So It is Low pass filter. Option B is correct.
