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? :3
AnswerAn insulator is a material with insufficient free charge carriers to support conduction.

Not a good electrical conductor or insulator?
babies, rocks, cabbage, and habberdasheries are neither good electrical conductors, nor insulators.
Why is magnesium oxide a good conductor?
Magnesium oxide is an electrical insulator.
Is plastic a good electrical conductor or insulator?
Plastic is made out of organic (carbon based) molecules which hold on to their electrons rather than contributing them to a common pool as metals do. Hence you do not get the kind of electron mobility needed for electrical conductivity.
Why do electrical wires covered with rubber?
AnswerBecause, it is a good insulator and won't conduct electricity. It is also flexible.It coated by rubber or plastic

Is Styrofoam a good conductor or a good insulator?
Electrical or thermal? Either way, it's an insulator.
Which is an example of a very good 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.
Is rubber a good electrical insulator?
Yes.
Is gold a good electrical insulator?
No! Its an excellent conductor.
Which of these would make a good electrical insulator?
rubber
What makes a good electrical insulator?
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.
A good insulator for electricity?
the best insulator is plastic. a better insulator is rubber which is used for wires and other electrical lines
Why is nylon a good insulator?
It is a good electrical insulator because it has no mobile electrons, unlike metals which have a populated conduction band.
What would make good electrical insulator?
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.
