Electricity 5.4a Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows electricity 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 to flow through it easily. Examples include rubber, glass, and plastic.

Front

Which material is a good conductor of electricity?

Back

Metal is a good conductor of electricity.

Front

What is an example of an insulator?

Back

Styrofoam is an example of an insulator.

Front

Is wood a conductor or an insulator?

Back

Wood is generally considered an insulator.

Front

What happens when electricity flows through a conductor?

Back

When electricity flows through a conductor, it can power devices and create heat.

Front

What happens when electricity flows through an insulator?

Back

Electricity cannot flow through an insulator, so it does not power devices.

Front

Name a common use for conductors.

Back

Conductors are used in electrical wiring to connect power sources to devices.

Front

Name a common use for insulators.

Back

Insulators are used to coat wires to prevent accidental electric shocks.

Front

What is the role of a conductor in an electrical circuit?

Back

The role of a conductor in an electrical circuit is to provide a path for electricity to flow.
