NEET 2011 Physics question

Not in JEE Advanced syllabus

In forward biasing of the p-n junction :

(1)the positive terminal of the battery is connected to p-side and the depletion region becomes thick
(2)the positive terminal of the battery is connected to n-side and the depletion region becomes thin
(3)the positive terminal of the battery is connected to n-side and the depletion region becomes thick
(4)the positive terminal of the battery is connected to p-side and the depletion region becomes thinCorrect

Answer: (4)

Solution

In forward bias the p-side is connected to the positive terminal and the n-side to the negative terminal. The applied field opposes the built-in barrier field, pushing holes and electrons
