1. What is an example of a semiconductor device?
LEDs!
2. Why is silicon used in the manufacture of semiconductors?
They use electronic conduction in the solid state instead of the gaseous state; it's more stable
3. Discuss the difference using an example of the difference between an N-type and P-type semiconductor.
N-type has a larger electron concentration while P-type has an larger hole concentration than electron concentration
4. In your own words describe what a diode does and the role of N and P type semiconductors.
A two-terminal electronic component that has low resistance to current in one side and high resistance to current in the other side; it is made from a p-n junction
5. What is rectification?
When a device converts AC to DC
6. What causes color in an LED? Give an example of what causes a particular color
Different wavelength ranges; Red is between 610nm and 760nm
7. What is the relationship between base current and collector current in a transistor?
The base current can be used to adjust the collector current
8. What are the advantages of a transistor over a switch?
A transistor lets you control the flow of electrons better.
