EVERYDAY SCIENCE

Detailed explanation-1: -Materials which do not allow an electric current to flow through them are known as insulators. The electrons in the insulators are bound to each other so tightly that there are no free electrons for the movement. that’s how electricity cannot be passed through them.

Detailed explanation-2: -insulator: a substance that does not allow electricity and/or heat to easily pass through it (“I” for I don’t think so!)

Detailed explanation-3: -Substances which allow heat to easily pass through them is termed as good conductor and those which do not are termed as bad conductor. Aluminium, copper and gold are few examples of good conductors of heat.

Detailed explanation-4: -An insulator is a material that does not allow a transfer of electricity or heat energy. Materials that are poor thermal conductors can also be described as being good thermal insulators. Feather, fur, and natural fibers are all examples of natural insulators.

Detailed explanation-5: -Insulators, on the other hand, don’t have free electrons and hence can’t conduct electricity.
