NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a p-n junction diode depicted with a depletion layer formed at the junction. Which of the following processes occurs when the diode is forward biased?
A
The potential barrier decreases, allowing current to flow.
B
The potential barrier increases, preventing current flow.
C
The depletion layer widens, reducing conductivity.
D
The depletion layer becomes positively charged.
Correct Answer
Option A
Detailed Explanation
In forward bias, the p-side is connected to the positive terminal and the n-side to the negative, decreasing the potential barrier and allowing charge carriers to flow across the junction.
