Electricity Circuits Quiz

What is a conductor?

• A person who directs an orchestra

• A material or device that allows the flow of electrical current

• A type of train ticket

• A type of insulator for electrical current

What is an insulator?

• A material or device that does not easily allow the flow of electricity or heat.

• A device that generates electricity or heat

• A type of conductor that enhances the flow of electricity or heat

• A material that easily allows the flow of electricity or heat

How does a conductor allow electricity to flow?

• By allowing the movement of electrons through their atomic structure

• By creating a barrier that blocks electricity

• By emitting electricity from their body

• By absorbing electricity like a sponge

How does an insulator prevent the flow of electricity?

• Insulators have high resistance to the flow of electricity.

• Insulators attract electricity towards them.

• Insulators have no effect on the flow of electricity.

• Insulators have low resistance to the flow of electricity.

What happens when a circuit is open?

• The resistance in the circuit decreases

• The circuit becomes more efficient

• The flow of electricity is interrupted.

• The flow of electricity increases

What happens when a circuit is closed?

• The circuit becomes inactive

• The circuit overheats and shuts down

• The circuit emits a strong odor

• Electric current flows through the circuit.

Explain how to draw a working circuit.

• Plan out the components and connections, use a circuit diagram, and physically assemble the circuit.

• Guess randomly and hope for the best

• Throw the components together and hope it works

• Ask someone else to do it for you
