A conductor is a material that allows electric current to flow through it easily, while an insulator is a material that resists the flow of electric current. Conductors have a high density of free electrons that are able to move in response to an electric field, while insulators have a low density of free electrons and do not allow current to flow easily. Examples of conductors include metals and some solutions, while examples of insulators include rubber, glass, and air.\n
