This car has a battery powered remote control that allows it to move, spin, honk, and light its headlights. Which of these describes one thing that could happen if the batteries die out?
The car's headlights will shine brighter.
The car's wheels will move slower.
The car's horn will not honk.
The car will spin faster.
A group of students built the circuit shown here. The light bulb does not glow. Which statement explains this observation?
The battery is not charged.
The light bulb is not part of a complete circuit.
The circuit does not have a switch.
The light bulb uses most of the energy from the battery.
All the lightbulbs in this circuit are lit. Which change would cause all the bulbs to go out?
Removing Wire 5
Removing Wire 3
Removing Wire 1
Removing Wires 3 and 4
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 NOT ring?
Bell 2 only
Bells 2 and 3 only
Bells 1 and 4 only
Bells 1, 2, 3, and 4
When the wires of this circuit are touched to this coin, the light bulb is lit. Why does this happen?
the coin is an insulator of electricity
the battery gives the energy to the coin
the coin is a conductor of electricity
the light bulb is a conductor of electricity
This circuit has a battery, buzzer, and switch.
When the switch is closed the buzzer will sound because -
the switch gives energy to the battery
the buzzer is made of special plastic
the wires are covered in plastic
electricity can flow in a complete path
Why is the cell phone charger covered in plastic?
Plastic is a conductor of electricity
Plastic helps electricity flow along the wire
Plastic is an insulator of electricity
Plastic adds more energy to a circuit
As this wind turbine turns, it changes _________.
Solar energy into electrical energy
Mechanical energy into electrical energy
Electrical energy into thermal energy
Mechanical energy into thermal energy
The main function of this kitchen appliance is to convert _________.
electrical energy into solar energy
Mechanical energy into thermal energy
electrical energy into light energy
electrical energy into thermal energy
All of the objects below are conductors of electricity EXCEPT–
Students constructed a circuit using different-colored lightbulbs. What will happen if Switch 1 is closed and the other switches are left open?
Only the red bulb will light up.
None of the bulbs will be light up
Only the white and yellow bulbs will light up.
Only the red and white bulbs will light up.
Which of these changes to the electric circuit shown will cause the lightbulb to light up? (5.6B)
Straightening the wire so that the current can flow more easily
Adding a switch and more wire so that the current can flow more easily
Turning one battery so that its positive end connects to the other battery's negative end
Making the length of wire the same on both sides of the lightbulb
How do you make an electromagnet stronger?
add another battery and/or another light bulb
Add more light bulbs and/or wire coils
add more wire coils and/or batteries
add more wire coils and/or paper clips
A student created the circuit above and discovered that the light bulb did not light up. What change can be made so that the light bulb can light up?
add a switch to the circuit
connect both wires to the other side of the light bulb
connect one of the two wires to the other side of the light bulb
add another battery to the circuit
What change would need to be made to allow both the bell and the bulb to function?
add another wire to the positive terminal of the battery
add a switch between the bell and the bulb
add another wire to the negative terminal of the battery
no changes are needed
