When a transistor is driven to cut off, ideally the output is _______________?
Correct answer: A. VCC
- A. VCC
- B. 0
- C. VCC/2
- D. VCC/3
Explanation
In the usual common-emitter transistor switch, cutoff makes collector current essentially zero, so there is no voltage drop across the collector load and the output rises to VCC. The result assumes the standard common-emitter switching arrangement.
