A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?

• Light bulb 1 and light bulb 2 will both be on

• Light bulb 1 will be off, but light bulb 2 will be on

• Light bulb 1 and light bulb 2 will both be off

• Light bulb 1 will be on, but light bulb 2 will be off

The diagram shows a series circuit with three lit bulbs. How many of the bulbs will remain lit if the wire is cut a the point shown by the arrow?

• 0

• 1

• 2

• 3

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

A simplified diagram of a system using solar energy is shown. To recharge the battery for later use without lighting the bulb, which of the following switches should be closed?

• switch S only

• switches R and S only

• switches R and T only

• switches R, S, and T
