Question:
If p-n junction diode is forward biased, then
If p-n junction diode is forward biased, then
Show Hint
Forward Bias = Narrow Depletion Layer = High Current.
Updated On: Jun 19, 2026
- electric conduction is not possible.
- width of depletion layer decreases.
- width of depletion layer increases.
- barrier voltage increases.
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Forward bias occurs when the p-side is connected to the positive terminal and the n-side to the negative terminal.
Step 2: Meaning
The applied potential opposes the built-in potential barrier.
Step 3: Analysis
This causes majority charge carriers to be pushed toward the junction, reducing the region depleted of mobile carriers.
Step 4: Conclusion
Consequently, the width of the depletion layer decreases. Final Answer: (B)
