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.

Why is magnesium oxide a good conductor?
Magnesium oxide is an electrical insulator.
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
Not a good electrical conductor or insulator?
Wood is not a good electrical conductor as it does not allow the flow of electricity easily due to its high resistance. However, it is also not a perfect insulator as it can conduct a small amount of electricity under certain conditions.
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.
Which mineral has a hardness of 2.5 3 and makes a good electrical insulator?
Biotite mica
Is copper an example of good electrical insulator?

Good electrical insulator?
Rubber.
Is acrylic a good electrical and thermal insulater?
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.
Is rubber a good electrical insulator?
Yes.
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 gold a good electrical insulator?
No! Its an excellent conductor.
Which of these would make a good electrical insulator?
rubber
A good insulator for electricity?
the best insulator is plastic. a better insulator is rubber which is used for wires and other electrical lines
Is fiberglass an insulator or a conductor?
Fiberglass is an insulator. Its properties make it a good electrical insulator because it does not conduct electricity well.
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.
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.
