Conductors and Insulators

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 wood.

Front

Which material is the best conductor of electricity?

Back

Copper is the best conductor of electricity among common materials.

Front

What is the role of insulators in electrical circuits?

Back

Insulators protect us from electric shock by preventing the flow of electricity to unwanted areas.

Front

Can plastic conduct electricity?

Back

No, plastic is an insulator and does not conduct electricity.

Front

What happens to heat when it passes through a conductor?

Back

Heat flows easily through a conductor, making it warm.

Front

What happens to heat when it passes through an insulator?

Back

Heat does not pass easily through an insulator, keeping the other side cooler.

Front

Is rubber a conductor or an insulator?

Back

Rubber is an insulator.

Front

What is an example of a good conductor?

Back

An example of a good conductor is silver.

Front

What is an example of a good insulator?

Back

An example of a good insulator is glass.
