what are insulators of electricity ?
Answers
Answer:
An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.
Any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator. Wood, plastic, rubber, and glass are good insulators. Swiss cheese... not so much.
The idea of an insulator comes from the Latin idea of insulātus, which means "to make into an island." This gives rise to the idea of separation, which works for the idea of an insulator, which effectively blocks energy. If your house is built out of good insulators, you might enjoy an island of warmth inside it even in the dead of winter.
