Question
In the circuit shown, assume that the opamp is ideal. If the gain () is , the value of (in ) is ______.
Correct answer
1 to 1
Solution
The op-amp is ideal, so (virtual ground).
Applying KCL at the inverting terminal:Applying KCL at node :Substituting :Given the gain is :Thus, the value of is 1.
