In a forward biased p-n junction diode, the width of the depletion region
- A.Increases
- B.Decreases
- C.Remains constant
- D.Becomes zero
Show correct answer & step-by-step solution
Correct answer: B — Decreases
Solution
When a p-n junction is forward biased, the external voltage opposes the built-in potential barrier. This pushes the majority charge carriers towards the junction, effectively reducing the width of the depletion region.
