ELECTRICAL CIRCUIT

Metal is used to make electrical wires because_______.

• It allows an electric current to freely flow.
• It slows electric currents from flowing.
• It is very cheap.
• It is very expensive.

Mrs. Moore made a circuit. It did not light up. Why?

• The switch is open.
• The switch is closed.

What is the function of the light bulb in a circuit?

• It increases the strength of the electricity.
• It changes electricity to light energy.
• It provides electricity to the battery.
• It opens and closes the circuit.

What is the type of circuit that stops working when one bulb goes out?

• A broken circuit
• Parallel Circuit
• Series Circuit
• A metal circuit

What are three things all circuits must have?

• Switch, conductor, light bulb
• Switch, conductor, power source
• Power source, conductor, load (light bulb)
• Conductor, resistor, switch

What is the energy source for a circuit?

• Light bulb
• Battery
• Wire
• Switch

What is it called when a circuit is complete?

• Closed circuit
• Light bulb circuit
• Open circuit
• Series circuit

Which of these materials is a good insulator?

• Plastic and metal
• Metal and rubber
• Plastic and rubber

This steel paperclip would allow electricity to flow through it because:

• it is a conductor

• it is an insulator

• it is friendly

• it breaks the circuit

This rubber ducky would block the flow of electricity, because:

• it is a conductor

• it is an insulator

• it is yellow

• it completes the circuit
