Question:

Forward biasing of a p-n junction

Options:

increases its resistance

decreases its resistance

increases the junction field

increases the potential barrier

Correct Answer:

decreases its resistance

Explanation:

The correct answer is Option (2) → decreases its resistance

In forward biasing of a p-n junction, the applied voltage reduces the potential barrier and allows majority carriers to cross the junction easily, thus the resistance decreases.

Answer: decreases its resistance
