NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about p-n junctions and their behavior under biasing conditions is correct?
A
In forward bias, the barrier potential decreases, allowing current to flow easily.
B
A p-n junction can only be formed by adding trivalent impurities to a semiconductor.
C
In reverse bias, the barrier potential decreases, resulting in increased current flow.
D
The depletion layer is formed by the movement of majority carriers across the junction.
Correct Answer
Option A
Detailed Explanation
In forward bias, the n-side is connected to the negative terminal and the p-side to the positive terminal, which decreases the barrier potential and allows current to flow easily. This is supported by the context stating that the barrier decreases in forward bias.
