The early effect in a bipolar junction transistor is caused by_______________?
Correct answer: C. large collector-base reverse bias
- A. fast turn-on
- B. fast turn-off
- C. large collector-base reverse bias
- D. large emitter-base forward bias
Explanation
The Early effect occurs when increased collector-base reverse bias widens the base depletion region and effectively narrows the base width. This raises collector current even when base current is held constant.
