## Homework Statement

Determine the Op amp gain of the following circuit.

V1 = 1v Vo = 4 V

## Homework Equations

A = Vo/ VI

## The Attempt at a Solution

Using voltage division I determined the voltage for the node at the +ve terminal

VI = V1(1k/ ([1000 + 1]k)) = 1/1001 V

Vo = 4v Given

Therefore A = Vo/VI = 4/(1/1001) = 4(1001)

However the answer is A = 4/(4/1001) = 1001

So somehow I'm off by a factor of 4. I am really unsure why VI is 4/1001.

Thank you so much for your time.
