Conductors, Semiconductors, and Insulators

Conductor

In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.

Inslulator

An Insulator is a material whose electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current

SemiConductor

SemiConductors allow electrical flow like a conductor but provides resistance,not as much as an insulator allowing slow electrical flow
