Conductors and Insulators Flashcard

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to flow through it easily. Examples include rubber, plastic, and glass.

Front

Which materials are good conductors of electricity?

Back

Good conductors of electricity include metals such as copper, aluminum, and silver.

Front

Which materials are good insulators of electricity?

Back

Good insulators of electricity include rubber, plastic, and glass.

Front

What is the main characteristic of insulators?

Back

Insulators do not conduct electricity easily.

Front

What is an example of a material that is an insulator of sound?

Back

Rubber is an example of a material that is an insulator of sound.

Front

Can water conduct electricity?

Back

Yes, water can conduct electricity, especially if it contains impurities.

Front

What is the role of insulators in electrical circuits?

Back

Insulators are used to prevent the unwanted flow of electricity, protecting users from electric shocks.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electricity to flow easily, while insulators resist the flow of electricity.
