- 1At the exact geometric center of the n-type silicon bar.
- 2Near the top edge, at 90% of the height from Base 1.
- 3Closer to Base 1, roughly at 10% of the height from Base 1.
- 4Closer to Base 2, roughly at 60% to 70% of the height from Base 1.✓
Correct answer
Closer to Base 2, roughly at 60% to 70% of the height from Base 1.
