Multiple Choice

A group of students built the circuit shown here. The lightbulb does not glow. Which statement explains this observation? (5.6B)

• 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.

Multiple Choice

Students constructed a circuit using different-colored lightbulbs. What will happen if Switch 3 is closed and the other switches are left open? (5.6B)

• 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.

Multiple Choice

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 lightbulbs. In which of these circuits will the other lightbulbs still light even if one bulb is burned out? (5.6B)

Multiple Choice

Why is electrical wiring usually made from copper?

• Because copper is shiny

• Because copper conducts electricity

• Because copper is not magnetic

• Because copper insulates electricity

Multiple Choice

If no changes are made to this circuit, what will the results be?

• Both bulbs are off because the switch is open

• Only the left bulb is lit because it has a closed path. The right bulb is not lit because of the open switch

• Both bulbs are lit because they each have a complete, closed path to the battery

• Only the right bulb is lit because an open switch causes the energy to flow to the bulb.
