Look at the picture to determine which statement is true.

• The light bulb will light up because the circuit is closed.

• The light bulb will not light up because the circuit is broken.

• The light bulb will light up because the circuit is open.

• The light bulb will light up because the insulator is closed.

If the light is off, the circuit is ______________________.

• Closed

• Compound

• Simple

• Open

Why are wires or other conductors in circuits often covered with insulators, such as rubber or plastic?

• It makes them look better.

• Insulation prevents electricity from passing through to you.

• It makes electricity pass therough the wire more efficiently.

• THe colors make it easy to tell which direction the electricity is flowing.
