5.6B Electrical Energy

What is a switch's function in a circuit?

• to make the current hotter or colder
• turn on and off the flow of current
• the pathway that current flows
• to add more power to the circuit

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

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

Most cars have lights, power locks, radios and other equipment that uses electricity. Electric circuits power this equipment. Each circuit has a fuse that completes it. The picture shows one type of fuse a car may have. Which of these describe one thing that could happen if the wire in a car fuse burns out?

• The car's light will burn brighter

• The car's radio will not work

• The car's turn signal will blink to slowly

• The car's power windows will open faster

A group of students built the circuit shown above. The lightbulb does not glow. Which statement explains this observation?

• The battery is not charged

• The lightbulb is not part of a complete circuit

• The circuit does not have a switch

• The bell uses most of the energy from the battery

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?

• switch S only

• switches R and S only

• switches R and T only

• switches R, S, and T

All the lightbulbs in this circuit are lit. Which change would cause all the bulbs to go out?

• Removing wire 1

• Removing wires 2 and 4

• Removing wires 2 and 5

• Removing wires 3 and 4

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
