Conductors and Insulators

Front

What are conductors?

Back

Materials that allow the flow of electricity or heat, such as metals.

Front

What are insulators?

Back

Materials that do not allow the flow of electricity or heat, such as rubber and glass.

Front

Give three examples of conductors.

Back

Copper, aluminum, and gold.

Front

Give three examples of insulators.

Back

Rubber, plastic, and wood.

Front

What is the main function of conductors?

Back

To facilitate the flow of electricity or heat.

Front

What is the main function of insulators?

Back

To prevent the flow of electricity or heat.

Front

How do conductors and insulators differ in terms of electron flow?

Back

Conductors allow electrons to flow freely, while insulators restrict electron flow.

Front

Why are metals good conductors?

Back

Metals have free electrons that can move easily, allowing electricity to flow.

Front

What is an example of a common use of insulators?

Back

Electrical wires are often covered with rubber or plastic to prevent electric shock.

Front

What happens to charge in a conductor when it is charged?

Back

The charge distributes itself uniformly throughout the conductor.
