In forward biasing of the p-n junction

Options

(a) the positive terminal of the battery connected to p-side and the depletion region becomes thick
(b) the positive terminal of the battery is connected to n-side and the depletion region becomes thin
(c) the positive terminal of the battery is connected n-side and the depletion region becomes thick
(d) the positive terminal of the battery is connected to p-side and the depletion region becomes thin

Correct Answer:

the positive terminal of the battery is connected to p-side and the depletion region becomes thin

Explanation:

In forward biasing of the p-n junction, the positive terminal of the battery is connected to p-side and the negative teminal of the battery is connected to n-side. The depletion region becomes thin.
