- 1The electron concentration in the n-region is greater compared to that in the p-region✓
- 2Only electrons move from the n to p region and not vice-versa
- 3Electrons travel across the junction due to a potential difference
- 4Holes in the p-region attract them
Correct answer
The electron concentration in the n-region is greater compared to that in the p-region
