Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow through it easily.

Front

Why are most pan handles covered in rubber?

Back

The rubber covering is an insulator and keeps the handle from becoming too hot.

Front

What type of materials are typically good conductors?

Back

Metals, such as copper and aluminum, are typically good conductors.

Front

Can electricity flow through all materials?

Back

No, not all materials allow electricity to flow through them.

Front

What is an example of an insulator?

Back

Plastic is an example of an insulator.

Front

What happens to the temperature of a conductor when electricity flows through it?

Back

The temperature of a conductor can increase when electricity flows through it due to resistance.

Front

What is the role of rubber in electrical appliances?

Back

Rubber acts as an insulator to prevent electric shock.

Front

Which material would allow electricity to pass through?

Back

Metal would allow electricity to pass through.

Front

What is the main difference between conductors and insulators?

Back

Conductors allow electric current to flow easily, while insulators do not.
