Insulators and Conductors

Front

What is an insulator?

Back

An insulator is a material that does not easily allow heat, electricity, light, or sound to pass through it. Examples include rubber, plastic, and glass.

Front

What is a conductor?

Back

A conductor is a material that allows electric charge to move through it as an electric current. Usually, the charge is carried by electrons, and the conductor is often a metal.

What is an example of a conductor?

Back

An example of a conductor is copper.

Front

What type of circuit allows multiple paths for electricity?

Back

A parallel circuit allows multiple paths for electricity.

Front

What type of circuit has only one path for electricity?

Back

A series circuit has only one path for electricity.
