Quiz about Electricity and Circuits (STAAR released questions)

Question 1

The circuit shown does not work.

Which procedure would most likely allow the bulbs to light?

Accepted Answer

Connect the two wires that are attached to the wood block.

Answer

Open the switch and then connect the two wires that are attached to the wood block.

Answer

Switch the positions of the two wires that are connected to the battery and then open the switch.

Answer

Move the switch closer in the circuit to the battery.

Question 2

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?

In which of these circuits will the other lightbulbs still light even if one bulb is burned out?

Accepted Answer

Question 3

All the lightbulbs in this circuit are lit.

Which change would cause all the bulbs to go out?

Accepted Answer

Removing wire 1

Answer

Removing Wires 2 and 4

Answer

Removing Wires 2 and 5

Answer

Removing Wires 3 and 4

Question 4

Students constructed a circuit using different-colored lightbulbs.

What will happen if Switch 3 is closed and the other switches are left open?

Accepted Answer

Only the white and yellow bulbs will operate.

Answer

Only the white bulb will operate.

Answer

None of the bulbs will operate.

Answer

Only the red and blue bulbs will operate.

Question 5

This circuit has three lightbulbs and a bell.

Which procedure will result in only the blue lightbulbs operating?

Accepted Answer

Close Switches 2 and 3 and leave Switch 1 open

Answer

Close Switches 1 and 2 and leave Switch 3 open

Answer

Close Switch 3 and leave Switches 1 and 2 open

Answer

Close Switch 2 and leave Switches 1 and 3 open

Question 6

A group of students built the circuit shown below.

The lightbulb does not glow. Which statement explains this observation?

Accepted Answer

The lightbulb is not a part of a complete circuit.

Answer

The battery is not charged.

Answer

The circuit does not have a switch.

Answer

The bell uses most of the energy from the battery.

Question 7

Many types of fans are used in homes. One type of electric fan is shown.

In addition to mechanical energy, which of these is produced (made) as electric current passes through the circuit of this fan?

Accepted Answer

Heat

Answer

Mass

Answer

Light

Answer

Water Vapor

Question 8

The diagram shows the metal posts that are usually found on a battery.

The battery can be connected to a bell and a switch to produce sound. Which statement best explains why there are two metal posts on the battery?

Accepted Answer

The battery needs to form a complete circuit that starts with one metal post and ends with the other metal post.

Answer

The battery needs only one metal post to connect to the bell, but the other metal post is present in case the first post fails to work.

Answer

One metal post makes a complete circuit with the switch, and the other metal post makes a complete circuit with the bell.

Answer

One metal post makes the bell start to ring, and the other metal post makes the bell louder.

Question 9

Most cars have lights, power locks, radios, and other equipment that use electricity. Electric circuits power this equipment.
For safety, each circuit has a fuse as part of the circuit. The picture below shows one type of fuse a car may have.

Which of these describes one thing that could happen if the wire in the fuse burns out?

Accepted Answer

The car's radio will not work

Answer

The car's lights will burn brighter

Answer

The car's turn signal will blink too slowly

Answer

The car's power windows will open faster

Question 10

The diagram shows a series 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?

Accepted Answer

0

Answer

1

Answer

2

Answer

3

Question 11

Which of these changes to the electric circuit will cause the lightbulb to light up?

Accepted Answer

Turning one battery so that its positive end connects to the other battery's negative end.

Answer

Straightening the wire so that the current can flow more easily.

Answer

Adding a switch and more wire so that the current can flow more easily.

Answer

Making the length of the wire the same on both sides of the lightbulb.

Question 12

A string of lights with small bulbs is shown below. The bulbs are connected by wire that is covered with an insulator.

When the lights are on, electricity travels in -

Accepted Answer

a complete circuit.

Answer

a sound wave.

Answer

a light ray.

Answer

an incomplete path.
