Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to pass 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 pass 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.

Front

What is the role of insulators in electrical wiring?

Back

Insulators protect us from electric shock by preventing the flow of electricity outside the wires.

Front

How does wool function as an insulator?

Back

Wool traps air, which slows down heat transfer, keeping warmth close to the body.

Front

Is plastic a conductor or an insulator?

Back

Plastic is an insulator.

Front

What happens to heat transfer in a conductor?

Back

In a conductor, heat transfer occurs easily and quickly.

Front

What is an example of a good insulator?

Back

Rubber is a good insulator.

Front

Why is copper used in electrical wires?

Back

Copper is used in electrical wires because it is an excellent conductor of electricity.

Front

What is the effect of using insulators in cold weather?

Back

Insulators help keep heat from escaping, keeping us warm.
