Exam-style question
Try this first
What is the primary assumption of an ideal operational amplifier?.
- A.It has finite input impedance.
- B.It has infinite open-loop gain.
- C.It cannot operate with negative feedback.
- D.It has a limited bandwidth.
Model answer
What a good answer should say
- It has infinite open-loop gain.
Explanation
Why this works
An ideal operational amplifier is assumed to have infinite open-loop gain, which allows it to amplify signals without any loss, making it a fundamental concept in op-amp applications.
