GATE ECE 2009 | Question-34

 

In the circuit shown below, the $\text{op-amp}$ is ideal, the transistor has $V_{B E}=0.6 \mathrm{~V}$ and $\beta=150$. Decide whether the feedback in the circuit is positive or negative and determine the voltage $V$ at the output of the $\text{op-amp.}$

  1. Positive feedback, $V=10 \mathrm{~V}$
  2. Positive feedback, $V=0 \mathrm{~V}$
  3. Negative feedback, $V=5 \mathrm{~V}$
  4. Negative feedback, $V=2 \mathrm{~V}$
