In forward bias and in reverse bias, respectively, the width of the depletion layer of a p-n junction
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → decreases; increases **
In a p–n junction:
• Under forward bias → the applied potential reduces the potential barrier.
→ Movement of charge carriers increases → depletion layer width decreases.
• Under reverse bias → the applied potential increases the potential barrier.
→ Movement of charge carriers decreases → depletion layer width increases.
Final Answer:
decreases; increases
