Q. In forward biasing of the p-n junction
A) The positive terminal of the battery is connected to p-side and the depletion region becomes thin
B) The positive terminal of the battery is connected to p-side and the depletion region becomes thick
C) The positive terminal of the battery is connected to n-side and the depletion region becomes thin
D) The positive terminal of the battery is connected to n-side and the depletion region becomes thick
Explanation
[Solution from source] In forward bias, the p-side is connected to the positive terminal; this opposes the built-in field and narrows the depletion region, letting current flow. Connecting the positive terminal to the n-side is reverse bias, which widens the depletion layer. Answer (1).
