- Find the voltage across R3
- Relevant Equations
- No current flows inside opamp
Here is question: Find voltage across R3
options:
10V
11V
5V
2V
Attempt: No current flows through Opamp, so 1mA flows through R3, this gives voltage across R3 = 1ma * 1K = 1V.
But that is not in option.
Where am I wrong? No current flows inside or outside opamp, right?
