Which of the lightbulbs in the diagram will light
up when the switch is closed?
To sound the buzzer without lighting up the
lightbulb, which switches should be closed?
Where can I cut the wire so that no light bulb turns on?
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?

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
Will the light bulbs light up in this image?
Yes, both of them will
Yes, but only the one on the right
No, neither of them will
Yes, but only the one on the left
Is this a working circuit?
Yes
No
I'm not sure, I would need to test it myself.
When the switch is closed the buzzer will sound because -
electricity can flow in a complete path (from one side of the battery to the other)
What is missing from this circuit? Why would the light bulbs be off?
The battery, there is no power for the circuit to work.
The switch is open, so the circuit is broken.
The third light bulb, that is needed to complete the circuit.
The wires are not connected properly.
