Question

Figure 2 This is modification of Figure 1 (added Q<sub>2</sub>, Q<sub>3</sub>, and R<sub>L</sub>, deletion of C<sub>3 </sub>and a changed value of R<sub>E1</sub>) . -Refer to Figure 2. Assume Vout has dropped to about 1/2 the expected value. A likely cause is that A) VCC is set to +15 V B) C2 is shorted C) R<sub>L</sub><sub> </sub>is open D) C<sub>2 </sub>is open

Quizplus · Accepted Answer

C2 is open, so there is no feedback to the op-amp. The op-amp will then saturate, and the output voltage will drop to a low value.
