Hello, I had a question in op amp?
If we provide equal dc voltages to an op amp it will produce some voltage 'Veq'.
The op amp has a finite gain. My understanding is, if we use this circuit in a negative feedback loop of another circuit X, its input voltages come closer to each other.
However they do not necessary become exactly equal. I think, they will become equal when the circuit X requires the op amp output voltage to be Veq for stabilization.
In other cases, when inputs are not exactly equal, what is this input difference called? Is it input offset voltage?
