Vo=rf/r1(v2-v1).

Vo=100k/100k(-1-1)=-2.

Shri said:   1 decade ago
v0=(1+rf/ri)*v1+v2 ......v2=0

Here, we can use {Rf÷R1}*(v1-v2).

Sugin V said:   8 years ago
Here, V2/2 (1+Rf/Rs) + V1 (-Rf/Rs).

Ananth said:   1 decade ago
Simulation result says -2v.

PUNAM said:   1 decade ago
Vo = -(Rf/R1)(V1-V2).

Sumit said:   1 decade ago
v0=(-rf/ri)(v1-v2)

Why v2 negative?
