MHT CET 2022 Physics question

Not in JEE Advanced syllabus

Reverse bias applied to a p-n junction diode

(A)increases the minority charge carriers.
(B)lowers the potential barrier.
(C)decreases the majority charge carriers.
(D)raises the potential barrier.Correct

Answer: (D)

Solution

In reverse bias the p-side is connected to the negative terminal and the n-side to the positive terminal of the battery. The external field is in the same direction as the junction (barrier) field, so holes and electrons are pulled away from the junction, the depletion layer widens and the potential barrier height
