This circuit has three lightbulbs and a bell.

Which procedure will result in only the blue lightbulbs operating?

• Close Switches 1 and 2 and leave Switch 3 open

• Close Switch 3 and leave Switches 1 and 2 open

• Close Switches 2 and 3 and leave Switch 1 open

A group of students built the circuit shown below.

The lightbulb does not glow. Which statement explains this observation?

• The battery is not charged.

• The lightbulb is not part of a complete circuit.

• The circuit does not have a switch.

• The bell uses most of the energy from the battery.

A string of lights with small bulbs is shown below. The bulbs are connected by wire that is covered with an insulator. When the lights are on, electricity travels in —
