Bell Work-10-28 5th

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 not light if the wire is cut a the point shown by the arrow?

• Bulb 1 will be on but bulb 2 and 3 will go off.

• Bulb 1, 2 and 3 will go off

• Bulb 2 will go off but bulb 1 and 3 will be on

• Bulb 1, 2 and 3 will stay on

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

Is the following photo of an open circuit or closed circuit? 

• A closed circuit which allows electricity to flow
• An open circuit which does not allow electricity to flow

Which best describes a simple series circuit?

• Electricity flows along one pathway.
• The flow of electricity comes from the switch.
• Electricity flows along many pathways.
• The flow of electricity comes from the light bulb.

What is a circuit with several paths for electricity to flow?

• conductor

• series circuit

• parallel circuit

• open circuit

A complete circuit has .......

• a motor in it
• a switch in it
• two bulbs in it
• no breaks in it

This circuit does not work. Which of these would 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

Some students built this circuit, but the bulb does not glow? Why doesn't the bulb glow?

• The battery is not charged.

• The bulb is not part of a complete circuit.

• The circuit does not have a switch.

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

Which is a good conductor?

• aluminum

• rubber

• paper

• plastic
