Arrange the following steps in the correct order to describe the functioning of an operational amplifier in a basic inverting amplifier configuration: A) The output voltage is fed back to the inverting input through a resistor, creating a feedback loop. B) The input signal is applied to the inverting input terminal. C) The op-amp amplifies the voltage difference between its inputs, resulting in an output voltage. D) The non-inverting input is connected to ground in this configuration.

Understanding the Answer

Let's break down why this is correct

First the input signal is applied to the inverting input. Other options are incorrect because This option puts grounding before the signal reaches the op‑amp; It suggests feedback occurs before the signal even reaches the op‑amp.

Operational amplifiers (op-amps) are devices that amplify the difference between their two inputs by a large gain factor. They have five terminals, including power supply terminals, inverting and non-inverting inputs, and an output terminal.
