What happens to the barrier potential of a p-n junction diode when it is forward biased?
A
The barrier potential decreases.
B
The barrier potential remains the same.
C
The barrier potential increases.
D
The barrier potential becomes zero.
Correct Answer
Option A
Detailed Explanation
In forward bias, the external voltage decreases the potential barrier of the p-n junction, allowing current to flow more easily.
