Conductors are materials in which an electric current can flow through the object easily. This is possible because its resistance is extremely low which allows the current to move without stopping.Conductors differ from insulators by them having a low amount of resistance[unlike insulators with a high resistance] but is similar to semi conductors in which that they both have a reasonable amount of non-resistance,with semiconductors having more resistance. Examples of conductors include: copper and iron and water.
SemiConductors are exactly what they sound like, they are conductors but have a slight increase in their resistance. This increase makes the semiconductor differ from a regular conductors resistance, but still has less resistance than a insulator does. The semiconductor lets currents pass through at a reasonable rate, letting its little resistance help to not make the current burn out. Types of semiconductors include: silicon and computer chips.
Insulators are what they sound like, they insulate electrical energy. They are able to do this because of their great deal of resistance. Insulators differ from conductors and semiconductors by the insulator having an extreme amount of resistance to electricity.They are similar (in a way) to semiconductors by the them both having an amount of resistance to electricity, but insulators have more than double the amount of resistance then a semiconductor has. Examples of insulators include: rubber, glass, and dry air.
