MHT CET 2026 Physics question

Not in JEE Advanced syllabus

If p-n junction diode is forward biased then

(A)width of depletion layer decreases.Correct
(B)width of depletion layer increases.
(C)barrier voltage increases
(D)electric conduction is not possible

Answer: (A)

Solution

In forward bias the external voltage opposes the built-in junction potential. Majority carriers are pushed towards the junction, which narrows the depletion layer and reduces the barrier voltage; once the applied voltage exceeds the knee voltage a
