A non inverting closed loop op amp circuit generally has a gain factor______________?
Correct answer: B. Greater than one
- A. Less than one
- B. Greater than one
- C. Of zero
- D. Equal to one
Explanation
A non-inverting amplifier has gain Av = 1 + Rf/R1, so with a normal positive feedback resistor its gain is greater than unity. A gain of exactly one is the special voltage-follower case, not the usual amplified configuration.
