Understanding the Answer
Let's break down why this is correct
Answer
First, the input signal is applied to the inverting input terminal (B). Then the non‑inverting input is tied to ground (D), making it a reference point. The output voltage is fed back through a resistor to the inverting input, forming a negative feedback loop (A). Because the op‑amp drives its output to keep the voltage difference between its inputs near zero, it amplifies that difference (C). For example, with a 10 kΩ feedback resistor and a 10 kΩ input resistor, a 1 V input produces a –1 V output.
Detailed Explanation
First the input signal is sent to the inverting input. Other options are incorrect because This option puts grounding after the input; It suggests feedback occurs before the input is applied.
