## Homework Statement

What is the output voltage for an op amp whose non-inverting input is connected to ground and its inverting-input voltage is 4mv? Assume that the op-amp open-loop gain is 2*10^5 and its supply voltage is Vcc=10V

## Homework Equations

Vo= A(vp-vn)

## The Attempt at a Solution

The problem gives

Vn= 4mv

A=2*10^5

Vcc=10V

Since it says the non-inverting input is connected to ground, does that mean vp=0?

Vo=2*10^5(0-.004V)

Vo=-800 V

However the answer is suppose to be -10V. What am I doing wrong?

Thanks for helping!
