Differentiate between conductors, semi-conductors, and insulators.
Question
Differentiate between conductors, semi-conductors, and insulators.
Solution
Conductors, semiconductors, and insulators are all materials that have different abilities to conduct electricity.
-
Conductors: These are materials that allow free flow of electrons from one particle to another. They are known for their high conductivity. This is because they have a large number of free electrons that can move easily. Examples of conductors include metals like copper, aluminum, and silver.
-
Semiconductors: These are materials whose properties can be varied between those of a conductor and an insulator. They have fewer free electrons than conductors, but more than insulators. Their conductivity increases with temperature, which is the opposite of what happens in conductors. Examples of semiconductors include silicon and germanium.
-
Insulators: These are materials that do not allow free flow of electrons from one particle to another. They have a very low number of free electrons, which makes them poor conductors of electricity. Their conductivity is almost zero. Examples of insulators include rubber, glass, and plastic.
