What is the combination of an npn transistor?
Options
- AThree layers of n-type semiconductors
- BOne layer of n-type and one layer of p-type semiconductor
- CTwo layers of n-type semiconductors and one layer of p-type semiconductor
- DTwo layers of p-type semiconductors and one layer of n-type semiconductor
Correct answer
C. Two layers of n-type semiconductors and one layer of p-type semiconductor
Step-by-step solution
An npn transistor is made by combining two layers of n-type semiconductors with one layer of p-type semiconductor.
