5.6B Electricity Fast Focus

The flow of electricity requires which type of circuit?

• open

• serial

• closed

• square

The picture shows an example of a simple circuit. The lightbulb will not light up because...

• there is no switch in the circuit.

• the wires do not form a closed circuit.

• the wires are too long.

• the lightbulb is broken.

What supplies the electrical energy in a circuit?

• the wires

• the lightbulb

• the battery

• the switch

Look carefully at the picture. Will the lightbulb light up in the circuit?

• No, because the circuit is not closed.

• Yes, because the penny is a good insulator.

• Yes, because the penny is a good conductor.

• No, because the penny blocks the flow of electricity.

In a simple series circuit, the lightbulb goes out when the switch is opened because...

• the switch provides the electricity.

• opening the switch breaks the closed circuit.

• the battery no longer works.

• the lightbulb breaks.

Which of the following is a correct definition of electricity?

• The flow of neutrons through a wire.

• The flow of atoms through a wire.

• The flow of air through a wire.

• The flow of electrons through a wire.

Study the picture. Will any of the lightbulbs light up in this circuit if the switch remains open?

• No, the circuit isn't closed with the switch open.

• Yes, only Bulb 3 will light up.

• Yes, Bulbs 2 and 3 will light up.

• Yes, Bulbs 1 and 3 will light up.

Study the picture. Which lightbulbs will remain lit if the wire is cut at the point where the scissors are located?

• Bulb 1 only

• Bulbs 1 and 2

• Bulbs 2 and 3

• None of the bulbs

Study the picture. The students were most likely trying to answer which question using the circuit shown?

• Does a wood block supply electrical energy?

• Does a circuit need a switch to work?

• Does wood conduct electricity?

• Can an electrical circuit ring a bell?

Study the picture. The lightbulb in the circuit will not work because...

• the lightbulb is broken.

• the battery is dead.

• there is no switch.

• the wires are connected incorrectly.
