MHT CET 2026 Physics question

Not in JEE Advanced syllabus

The depletion region of p-n junction

(A)increases if reverse biased.Correct
(B)increases if forward biased.
(C)decreases if reverse biased.
(D)remains same in reverse and forward biasing.

Answer: (A)

Solution

Under reverse bias the external battery pulls the majority carriers (holes in p-side, electrons in n-side) away from the junction, so more immobile ions are uncovered and the depletion layer widens; the barrier potential increases and only a tiny
