Electricity and Circuits (STAAR released questions)

This circuit has five light-emitting diode, or LED, lights. It also has one battery and one switch.

Which LEDs produce light when the switch is in the position shown?

The circuit shown does not work.

Which procedure would most likely allow the bulbs to light?

• Open the switch and then connect the two wires that are attached to the wood block.

• Switch the positions of the two wires that are connected to the battery and then open the switch.

• Move the switch closer in the circuit to the battery.

• Connect the two wires that are attached to the wood block.

The diagram shows an electric circuit with four bells that a student plans to build.

When the student connects the wires as shown, which of the bells will ring?

In some circuits that are used for decorating, one burned-out lightbulb will prevent all the other lightbulbs from lighting. In other circuits, one burned-out lightbulb will have no effect on the other lightbulbs.

In which of these circuits will the other lightbulbs still light even if one bulb is burned out?

• 
• 
• 
• 

All the lightbulbs in this circuit are lit.

Which change would cause all the bulbs to go out?

• Removing wire 1

• Removing Wires 2 and 4

• Removing Wires 2 and 5

• Removing Wires 3 and 4

Students constructed a circuit using different-colored lightbulbs.

What will happen if Switch 3 is closed and the other switches are left open?

• Only the white bulb will operate.

• None of the bulbs will operate.

• Only the white and yellow bulbs will operate.

• Only the red and blue bulbs will operate.

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

• Close Switch 2 and leave Switches 1 and 3 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 a part of a complete circuit.

• The circuit does not have a switch.

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