MHT CET Physics question

Not in JEE Advanced syllabus

When a p-n junction diode is reverse biased

(A)electrons and holes are attracted towards each other and move towards the depletion region
(B)electrons and holes move away from the depletion regionCorrect
(C)height of the potential barrier decreases
(D)no change in the current takes place

Answer: (B)

Solution

In reverse bias the applied field pulls the majority electrons and holes away from the junction, so the depletion region widens and the barrier height increases; (a)
