GEOLOGY

Detailed explanation-1: -Materials that do not allow electricity to pass through them are called insulators. Insulators oppose electric current and so they are used as a protection from the dangerous effects of electricity. Examples of insulators are glass, air, wood, plastic and rubber.

Detailed explanation-2: -Difference between conductors and insulators Plastic, wood, rubber glass etc are insulators.

Detailed explanation-3: -An Insulator like wood and rubber has a very high electrical resistance because they don’t have free electrons to conduct current.

Detailed explanation-4: -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.
