Question

Consider the circuit shown in the figure below:

Assuming the op-amp to be ideal, then the value of output voltage V0 is _____ V
  1. 3

Open in App
Solution

The correct option is A 3

Since, negative feedback is applied to the op-amp, thus the concept of virtual ground is applicable


Thus, Va=Vb

Now, since the op-mp is ideal thus Iin=0

Hence V0=Vb2V=5V2V

=3V
