Question & Answer
Choose the Best Answer
To amplify the difference between two input signals
To filter out unwanted noise
To provide power supply voltage
To convert analog signals to digital signals
Understanding the Answer
Let's break down why this is correct
The transistors inside the op‑amp act like a chain of small switches that boost the voltage difference between the two input pins. Other options are incorrect because Some think the transistors clean up noise because op‑amps are used in filters; A common idea is that the transistors provide the supply voltage.
