Question
When negative feedback is established in an op amp circuit by connecting the output terminal through a network to the inverting input terminal, what is the value of the voltage at the inverting input?
Step 1
Negative feedback occurs when a portion of the output voltage is fed back to the inverting input terminal, which helps stabilize the gain and improve linearity. Show more…

The output voltage of an op amp is $-4 \mathrm{V}$ when the noninverting input is $1 \mathrm{mV}$. If the open-loop gain of the op amp is $2 \times 10^{6},$ what is the inverting input?
