-Refer to Figure 5. The primary purpose of Rf is to
A)provide a path for bias current 
B)prevent noise from affecting the output 
C)attenuate the signal 
D)avoid drift

Quizplus · Accepted Answer

Rf is typically used in feedback circuits to stabilize the output and avoid drift by providing a stable reference point.
