Analog Electronics Quiz EXPLANATIONS:
- Ohm’s law, J = σE
3. For reverse biased, the depletion region is highest. Next is no biased and the lowest is for forward biased.
4. For n-type semiconductor, electrons are major charge carriers. And holes are minor.
5. Ge is a semiconductor so it has negative coefficient of temperature. Conductors have positive value.
7. Hole is the majority charge carrier in p-type semiconductor. Electrons are minor.
8. Width of depletion region decreases as the forward voltage increases and vice versa.
9. There is no acceptor atom in n-type semiconductor. So its concentration is zero.
10. Width increases as the reverse biased voltage increases.
