Exam-style question
Try this first
In an ideal operational amplifier, what is assumed about the gain?.
- A.The gain is variable
- B.The gain is finite
- C.The gain is infinite
- D.The gain is negative
Model answer
What a good answer should say
- The gain is infinite
Explanation
Why this works
An ideal operational amplifier is assumed to have infinite gain, which allows it to amplify even the smallest input signals to a significant output level.
