copper
Insulator is a material that resists the flow of electric current. materials such as glass, paper or Teflon are very good electrical insulators. These materials are used to support or separate electrical conductors without passing current through themselves.
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
yes it is a very good one
An insulator is something that stops the transmissions of the different types of energy from one place to another. One example is insulation (such as fiberglass in your walls or attic); another example is the rubber coating on electric cords to keep sparks or electricity from escaping.
wool is a insulator
The best insulator for walls depends on factors like cost, effectiveness, and environmental impact. Common options include fiberglass, cellulose, and foam insulation. Foam insulation, such as spray foam or rigid foam boards, is considered one of the most effective insulators but can be more expensive.
A good conductor of electricity is copper, which allows electrons to flow easily, while a good insulator is rubber, which restricts the flow of electrons due to its high resistance.
Mica is an insulator of electricity and heat.
The poorest insulator would be the best conductor, which is one of the noble metals. Bakelite is a fairly good insulator, not too long ago electrical fittings were made from it.
It's more of a conductor, but not a very good one.
Yes, asbestos is an excellent heat insulator. That was one major reason it was widely used in ships and in heating plants.
No, gold is a metal and therefor a conductor. A very good one actually.
