Conductors and Insulators Practice

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electric current or heat. Common conductors include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow the flow of electric current or heat. Examples include rubber, glass, and plastic.

Front

True or false: All metals are conductors.

Back

True. Most metals are good conductors of electricity and heat.

Front

Which of the following is a good conductor of electricity: rubber, copper, or wood?

Back

Copper is a good conductor of electricity.

Front

What is the primary characteristic of materials that are good conductors?

Back

Good conductors have free electrons that can move easily, allowing electric current to flow.

Front

True or false: Plastic is a good conductor of heat.

Back

False. Plastic is an insulator and does not conduct heat well.

Front

What is the relationship between electrical conductivity and thermal conductivity?

Back

Materials that are good conductors of electricity are often also good conductors of heat.

Front

Name a common use for conductors in everyday life.

Back

Conductors are used in electrical wiring, circuit boards, and electronic devices.

Front

What type of material is typically used for electrical insulation?

Back

Materials like rubber, plastic, and glass are commonly used for electrical insulation.

Front

True or false: A rubber eraser is a conductor of electricity.

Back

False. A rubber eraser is an insulator.
