Question:

In forward biasing of the p – n junction:

Options:

the positive terminal of the battery is connected to p – side and the depletion region becomes thick

the positive terminal of the battery is connected to n – side and the depletion region becomes thin

the positive terminal of the battery is connected to n – side and the depletion region becomes thick

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, 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.
