Answer:
1.Materials that allow electricity to pass through them are called conductors. Copper wire is a good conductor. Materials that do not allow electricity to pass through them are called insulators. Plastic is a good insulator.
2.Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity. This is why electrical wires are covered in rubber, plastic, or cloth.
3.Materials that allow electricity to pass through them are called conductors. Copper wire is a good conductor. Materials that do not allow electricity to pass through them are called insulators. Plastic is a good insulator.
4.Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.
