If $\mathrm { R } _ { \mathrm { i } } = 1 \mathrm { k } \Omega , \mathrm { R } _ { f } = 100 \mathrm { k } \Omega$ and V_OUT =5 V in a noninverting op-amp, ACL equals_____ A) 0.0099 B) 99 C) 101 D) 1

Question

Quizplus · Accepted Answer

The formula for calculating the gain (ACL) of a noninverting op-amp is:

ACL = 1 + (Rf/Ri)

Substituting the given values, we get:

ACL = 1 + (100kΩ/1kΩ) = 101

Therefore, the best choice is C, as it gives the correct ACL value for the given circuit.

If Ri=1kΩ,Rf=100kΩ\mathrm { R } _ { \mathrm { i } } = 1 \mathrm { k } \Omega , \mathrm { R } _ { f } = 100 \mathrm { k } \OmegaRi​=1kΩ,Rf​=100kΩ

If $\mathrm { R } _ { \mathrm { i } } = 1 \mathrm { k } \Omega , \mathrm { R } _ { f } = 100 \mathrm { k } \Omega$
