Given that the op-amps in the figure are ideal, the output voltage V0 is
-
- (V1 – V2)
- 2(V1 – V2)
- (V1 – V2 ) / 2
- (V1 + V2)
Correct Option: B
| + | = 0 | |||
| 2R | R |
| ∴ V02 = | .....(i) | |
| 2 |
| + | = 0 | |||
| 2R | R |
| ∴ V01 = | ......(ii) | |
| 2 |
∵ I1 = If
 | V02 - |  | = | | - V0 | | |||
| 2 | 2 | ||||||||
| R | R | ||||||||
From equation (i) and (ii)
∴ V0 = V01 – V02
| = | | | - | | | |||
| 2 | 2 |
V0 = 2(V1 – V2)
