1. Diodes and Transistors are examples of semi-conductor devices.
2. Silicon tends to be cheaper than other materials. It also has a wide temperature range and has a high purity of 99.99%
3. N-type semiconductors have negative electron properties. P-type semiconductors have positive properties, they are missing an electron.
4. Diodes consist of p and n type semiconductors. This allows electrical current flow in one direction with a wall in-between them.
5. This allows current to flow in one direction.
6. The raw materials in the semiconductor creates the color, by changing the raw material you can change the color.
7. Base current is when current flows from the base to the emitter. Collector current is when current goes from the collector to the emitter. The collector current thus gets bigger than the base current.
8. A transistor does not get worn out easy, its also doesn't fail, and can be more precise when controlling it.
