Understanding the Answer
Let's break down why this is correct
An op‑amp’s job is to take the tiny voltage gap between its two pins and magnify it. Other options are incorrect because Some think an op‑amp multiplies its inputs because the term amplifier suggests more; Adding the two voltages would give the sum of vp and vn, but an op‑amp does not add them.
