Rubber.
yes copper is a good eletrical insulator
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.
Yes.
Acrylic is not a good electrical insulator because it is a conductor of electricity. However, it can be a good thermal insulator as it has low thermal conductivity.

No! Its an excellent conductor.
rubber
the best insulator is plastic. a better insulator is rubber which is used for wires and other electrical lines
Fiberglass is an insulator. Its properties make it a good electrical insulator because it does not conduct electricity well.
An electrical insulator is a material whose internal electric charges do not flow freely. Rubber, glass, paper, and Teflon, which have high resistivity, are very good electrical insulators.
An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.
It is a good electrical insulator because it has no mobile electrons, unlike metals which have a populated conduction band.
