Grade 5 Electricity Quiz

What is a conductor?

• Something that does not allow electricity to flow through it.

• Something that allows electricity to flow through it.

• Something that causes a change.

• Something that makes people move.

Which of the following is an example of a conductor?

• Copper

• Plastic

• Rubber

• Wood

What is an insulator?

• A device that amplifies sound

• A material that does not conduct electricity or heat.

• A material that conducts electricity and heat

• A substance that repels water

Name a material that is a good insulator.

• Rubber

• Water

• Metal

• Glass

What is an open circuit?

• A circuit with uninterrupted current flow

• A circuit with no resistance

• A circuit with excessive current flow

• A circuit where there is an opening in the circuit, preventing the flow of the electric current.

What is a closed circuit?

• A closed circuit allows electricity to flow continuously without interruption.

• A closed circuit only allows electricity to flow in one direction.

• A closed circuit requires a power source to function.

• A closed circuit is only used in advanced electrical systems.

What is an electromagnet?

• A magnet made of pure gold

• A magnet that only works in outer space

• A magnet that is powered by solar energy

• A type of magnet in which the magnetic field is produced by an electric current

How is an electromagnet different from a permanent magnet?

• An electromagnet requires an electric current to produce a magnetic field, while a permanent magnet does not.

• An electromagnet is made of wood, while a permanent magnet is made of metal.

• An electromagnet is only used in space, while a permanent magnet is only used on Earth.

• An electromagnet is invisible, while a permanent magnet is visible.

What is electric current?

• The movement of water through a pipe

• The flow of electric charge through a conductor.

• The process of converting heat into energy

• The transfer of sound waves through a medium

Describe the flow of electric current in a circuit.

• The electric current flows from the positive side of a source, through the conductive material, and back to the negative side of the source.

• The electric current flows only when the circuit is turned off.

• The electric current flows in a random pattern within the circuit.

• The electric current flows from the negative terminal of the voltage source, through the conductive material, and back to the positive terminal of the voltage source.
