Electric Circuits 5.6B 2

What is a conductor?

•  A material that allows electricity to flow through it.  The circuit is complete. 
• A material that does not allow electricity to flow through.  It stops the flow of electricity.
• A light switch.

An example of an insulator is?

• metal
• plastic
• brass
• aluminum

Most cars have lights, power locks, radios and other equipment that uses electricity. Electric circuits power this equipment. Each circuit has a fuse that completes it. The picture shows one type of fuse a car may have. Which of these describe one thing that could happen if the wire in a car fuse burns out?

• The car's light will burn brighter

• The car's radio will not work

• The car's turn signal will blink to slowly

• The car's power windows will open faster

• Removing wire 1

• Removing wires 2 and 4

• Removing wires 2 and 5

• Removing wires 3 and 4
