第一章测验
1、单选题：
A p-n junction is forward biased when ____.
选项：
A: the applied potential causes the n-type material to be more positive than the p-type material
B: the applied potential causes the n-type material to be more negative than the p-type material
C: both materials are at the same potential
D: None of these
答案: 【 the applied potential causes the n-type material to be more negative than the p-type material 】
2、单选题：
A p-n junction is reverse biased when _______.
选项：
A: the applied potential causes the n-type material to be more positive than the p-type material
B: the applied potential causes the n-type material to be more negative than the p-type material
C: the current flow across the junction is based on minority carrier transfer
D: All of the above
答案: 【 the applied potential causes the n-type material to be more positive than the p-type material 】
