Question
For the circuit shown below, assume that the OPAMP is ideal.
Correct answer
(C) vₒ = 2.5 vₛ
Solution
Given that the OPAMP is ideal, we use the virtual short concept: .
1.Calculate at the non-inverting terminal using the voltage divider rule:
Therefore, .2.Apply KCL at the inverting terminal node:
3.Apply KCL at node :
Thus, the correct option is (C).Continue learning with Success Tracker
