A certain noninverting amplifier has Ri of 1 kO and Rf of 100 kO. The closed-loop voltage gain is_____________?
Correct answer: C. 101
- A. 100,000
- B. 1000
- C. 101
- D. 100
Explanation
For a non-inverting amplifier, the closed-loop gain is 1 + Rf/Ri. Substituting the values gives 1 + 100 kΩ/1 kΩ = 101.
