Conductor , Semiconductor and Insulators .
- Conductors are materials that are freely allow the flow of electrons with very little resistance. Conductor allows the electrical current in one or more direction,A wire is an electrical conductor that can carry electricity along its length. An Example: Conductor would be things like Water,Copper,Iron.
Semiconductors are materials that do not allow electrons to flow freely but do not directly stop them either.Semiconductor have more resistance that the conductor releases less energy. Example of Semiconductor is :Silicon ( used in computer).
Insulators are materials that greatly impede or stop flow of electrons with very high resistance . Stops currents from flowing freely and most non-metallic are said to be good insulators. A good example of insulators are ,Glasses , Dry Air , and Rubber .
