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, glass, and wood.

Front

Is the human body a conductor?

Back

True, the human body is a conductor because it contains water and electrolytes that allow electricity to flow.

Front

What happens to heat transfer?

Back

Heat transfer always goes from hot to cold.

Front

Give an example of a good conductor.

Back

Copper is a good conductor of electricity.

Front

Give an example of a good insulator.

Back

Rubber is a good insulator and is often used to cover electrical wires.

Front

What is the role of conductors in electrical circuits?

Back

Conductors allow electric current to flow through the circuit, enabling devices to function.

Front

What is the role of insulators in electrical circuits?

Back

Insulators prevent the flow of electricity, protecting users from electric shock and ensuring that current flows only where it is intended.

Front

Can air be a conductor?

Back

Air is generally a poor conductor, but under certain conditions (like high voltage), it can conduct electricity.

Front

What is thermal conductivity?

Back

Thermal conductivity is a measure of how well a material conducts heat. High thermal conductivity means the material is a good conductor of heat.
