Electricity and circuits quiz 1 by Gavin Thomas November 26, 2023, 4:34 pm Welcome to your Electricity and circuits quiz 1 Ýour teacher email Your name Your school 1. The diagram shows an electric circuit with four bells that a student plans to build. When the student connects the wires as shown, which of the bells will ring? Bell 1 only Bells 1 , 3 and 4 only Bells 3 and 4 only Bells 1, 2, 3, and 4 None 2. Students constructed a circuit using different-colored lightbulbs. What will happen if Switch 3 is closed and the other switches are left open? 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 None 3. Why is that household electrical appliances are not usually connected in series? Switching off one appliance would switch off the rest Because when one appliance is used, the fuse will blow up Because there will be interference as soon as two or more appliances are used Because there will be an increase in power consumption None 4. How does a switch turn a bulb off? By removing the bulb By removing the wire By breaking the circuit By completing the circuit None 5. This circuit has three lightbulbs and a bell. Which procedure will result in only the blue lightbulbs operating? Close Switches 2 and 3 and leave Switch 1 open Close Switch 2 and leave Switches 1 and 3 open Close Switch 3 and leave Switches 1 and 2 open Close Switches 1 and 2 and leave Switch 3 open None 6. A simplified diagram of a system using solar energy is shown. To recharge the battery for later use without lighting the bulb, which of the following switches should be closed? Switches R and S only Switch S only Switches R, S, and T Switches R and T only None 7. Most cars have lights, power locks, radios, and other equipment that use electricity. Electric circuits power this equipment. Each circuit has a fuse that completes it. The picture below shows one type of fuse a car may have. Which of these things describes one thing that could happen if the wire in a car fuse burns out? The car's lights will burn brighter. The car's radio will not work. The car's turn signal will blink too slowly. The car's power windows will open faster. None 8. What is the source of power in a circuit Battery Wire Bulb Switch None 9. In a home, the circuits will be... Parallel Series Complex Simple None 10. What is the purpose of a switch in an electrical circuit? To turn the power on and off To complete the circuit To turn the power on To turn the power off None 11. The diagram shows a circuit with three lit bulbs. How many of the bulbs will remain lit if the wire is cut at the point shown by the arrow? 0 1 2 3 None 12. How can you make a bulb brighter in a circuit? By removing a battey By adding a battery Use a brighter bulb Adding a motor None 13. What does the fuse do in a plug? make the battery last longer keep the electricity flowing Stop a surge of electricity to the devise cause the doorbell to ring None 14. What type of circuit is shown in the diagram Series Parallel None 15. A group of students built the circuit shown below. The lightbulb does not glow. Which statement explains this observation? The circuit does not have a switch The battery is not charged The bell uses most of the energy from the battery. The lightbulb is not part of a complete circuit None 16. 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 other lightbulbs. In which of these circuits will the other lightbulbs still light even if one bulb is burned out? A series circuit A open circuit A parallel circuit An incomplete circuit None 17. All the lightbulbs in this circuit are lit. Which change would cause all the bulbs to go out? Removing Wires 2 and 4 Removing Wires 3 and 4 Removing Wire 1 Removing Wires 2 and 5 None Time's upSee morePrevious article Science Examination quiz 2Next article Caricom quiz 1 Written by Gavin ThomasLeave a ReplyYou must be logged in to post a comment.
