Which part of the material is the Insulator?

pick all best answers.

• metal is a conductor

• the plastic is an insulator to contain the electrical charge

• the plastic is an Conductor to contain the electrical charge

• metal is a insulator

Multiple Choice

What are insulators?  

• A conductor is a material that allows electric charge to move through it as an electric current. Usually the charge is carried by electrons, and the conductor is a metal.
• An object that is really, really, really, and I mean really truely, awesome.
• A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators. Compare conductor.
