A Conductor is a material that can conduct Electric Current easily, because its Resistance to flow of Current is low.  Many Conductors are metallic, like copper , iron etc. but there are some non-metallic Conductors too, like carbon and argon

An insulator is a material that does not conduct electrical current. It restrict the flow of current.

Insulating materials include paper, plastic, rubber, glass and air.

Materials that have high resistance to electric current are called electric insulators. Insulators are placed in household items and electrical circuits as protection.

Thermal insulation is similar, but it constricts the flow of heat rather than electricity. .
