Circuits

A class prepared some electrical circuits using battery, connecting wires, and three light bulbs.  Which of these circuits can make the three bulbs light?

• A
• B
• C
• D

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?

• 0

• 1

• 2

• 3

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

• a complete circuit

• a sound wave

• a light ray

• an incomplete path

In the picture, if you replace the paper clip with a plastic spoon, what happens? 

• The bulb doesn't light
• The bulb is dimmer
• The wires get hot
• There is no charge

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

Why does the following circuit not work?

• The light bulb is broken

• The switch is closed

• The wood block is an insulator

• The battery is dead

The circuit does not work, what could you do to allow the circuit to work?

• Add another light

• Add another battery

• Open the switch

• Remove the wood block and connect the wires
