NEET Physics (general) MCQ Question
Which of the following statements correctly describe the behavior of a p-n junction under forward bias?
The depletion layer width decreases and the barrier height is reduced, allowing more carriers to cross the junction.
The majority carriers in the p-region become holes while in the n-region they become electrons, leading to an increase in resistance.
Only a small number of electrons from the n-side can cross the junction at low forward biases, resulting in negligible current.
Under forward bias, the barrier height increases, making it harder for carriers to cross the junction.
Correct Answer
Detailed Explanation
Under forward bias, the depletion layer width decreases and the effective barrier height reduces, allowing for more carriers to cross the junction, leading to increased current as described in Chunk 1.
