Question

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 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 to 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.

Answer 1

Answer: (D)

In forward biasing, the positive terminal of the battery is connected to $p$-side and the negative terminal to $n$-side of $p-n$ junction. The forward bias voltage opposes the potential barrier. Due to it, the depletion region becomes thin.
