Which of the following is a key feature of a non‑inverting amplifier configuration?.
- A.Input connected to inverting terminal
- B.Output is inverted
- C.Feedback resistor from output to inverting terminal
- D.No feedback resistor
Model answer
What a good answer should say
- Feedback resistor from output to inverting terminal
Explanation
Why this works
Formula/rule: A non‑inverting amplifier requires a feedback resistor from the output to the inverting (−) terminal. Substitution: The circuit includes this feedback resistor.
Working: This matches the key feature of a non‑inverting amplifier. Answer: Feedback resistor from output to inverting terminal.
Units/conclusion: The circuit is a non‑inverting amplifier.
