Question
Explain how the width of depletion layer in a p-n junction diode changes when the junction is (i) forward biased (ii) reverse biased.
✓
Answer
- In forward biasing, the depletion layer decreases.
Reason: Majority charge carriers come closer to junction.
- In reverse biasing, the width of depletion layer increases.
Reason: The majority charge carries go farther away from the junction.
