A given p-n junction is forward biased. Which of the following statements is correct?

The height of potential barrier is decreased.

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.
