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.

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, glass, and wool.

What happens in an open circuit?

Back

In an open circuit, the path for electricity is broken, and the light or device does not work.

Front

What happens in a closed circuit?

Back

In a closed circuit, the path for electricity is complete, and the light or device works.

Front

Can an insulator ever be a good conductor?

Back

No, an insulator cannot be a good conductor; they have opposite properties.

What is an example of a material that is both a conductor and an insulator?

Back

Water can conduct electricity under certain conditions but is generally considered an insulator.
