Question:
If no external voltage is applied across p-n junction, there would be
If no external voltage is applied across p-n junction, there would be
Show Hint
Built-in field opposes further diffusion of majority carriers.
Updated On: Apr 7, 2026
- no electric field across the junction
- an electric field pointing from n-type to p-type side across the junction
- an electric field pointing from p-type to n-type side across the junction
- a temporary electric field during formation of p-n junction that would subsequently disappear
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Built-in potential exists at p-n junction.
Step 2: Detailed Explanation:
Positive charge on n-side, negative on p-side creates field from n to p.
Step 3: Final Answer:
Electric field points from n-type to p-type.
