In forward bias and in reverse bias, respectively, the width of the depletion layer of a p-n junction
- A decreases; increases
- B increases; decreases
- C decreases; decreases
- D increases; increases
Answer & Solution
Correct Answer
(A) decreases; increases
Step-by-step Solution
Detailed explanation
In forward bias, the width of the depletion layer decreases as charge carriers are pushed toward the junction. In reverse bias, the width increases as carriers are pulled away. Therefore, the correct option is A.
