A given p-n junction is forward biased. Which of the following statements is correct?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → The height of potential barrier is decreased.
In forward bias of a p–n junction:
• Electrons move from n-region to p-region (not p to n).
• The height of potential barrier is reduced because the applied voltage opposes the junction potential.
• The width of depletion region decreases.
Answer: The height of potential barrier is decreased.
