MHT CET 2023 Physics question

Not in JEE Advanced syllabus

If p-n junction diode is in forward bias then

(A)width of depletion layer increases
(B)electric conduction is not possible at all
(C)barrier voltage increases
(D)width of depletion layer decreasesCorrect

Answer: (D)

Solution

In forward bias the external battery drives holes from the p-side and electrons from the n-side towards the junction. These carriers neutralise part of the immobile ions in the depletion region, so the depletion layer becomes narrower, the barrier potential is reduced and a
