Manga 4

1. What is an example of a semiconductor device?

Resistor

2. Why is silicon used in the manufacture of semiconductors? 

It is refined to be virtually 100% pure.

3. Discuss the difference using an example of the difference between and N-type and P-type semiconductor.

P means it is Positive for holes. N means Negative for electrons. N-type is a negative semiconductor. P-type is a positive semiconductor. P-type has excess holes and missing electrons while n-type has free electrons.

4. In your own workd describe what a dioode does and the role of N and P type semiconductors.

A diode allows electrical current to flow in one direction. A diode is made up of p-type and n-type semiconductors.  Made from p-n junction.

5. What is rectification?

It allows current to flow in one direction.

6. What causes color in an LED? Give and example of what causes a particular color.
An LED emits light when it is activated at the P-N junction. An LED releases photons(energy) and the light color correlate. The material used in the semiconducting element of an LED determines its color. LED's that emit different colors are made of different semi-conductor materials.

7. What is the relationship between base current and collector current in a transistor?
Base current is where the current flows from the base to the emitter with collector current as the base current flows, current from the collector begins to flow to the emitter as well.

8. What are the advantages of a transistor over a switch? 

Transistor has no contact, it’s easy to use, less likely to have damage, faster, and you have more control.
