Open and Closed Circuits

Electrical lights will not come on unless their electrical circuit is a --

• parallel circuit

• series circuit

• closed circuit

• open circuit

Will the light bulb in this circuit light and why/why not?

• yes, because it has two batteries
• no, because the switch is open
• yes, because it is in a circuit
• no, because the bulb is burned out

What would happen if the switch was opened?

• nothing, the light bulbs would still work because there is a complete path
• The light bulbs would not work because the path was broken
• the battery would loose energy
• the wires would be cooled from air

The on switch shows

• An open circuit where electricity can flow
• A closed circuit that is also called complete
• not related to circuits
• An incomplete circuit that does not allow electricity to flow

A open circuit allows charges to flow. 

• True 
• False

Which statement is true?

• The light bulb will light up because the  circuit is complete.
• The light bulb will light up because the  circuit is broken.
• The light bulb will not light up because the  circuit is complete.
• The light bulb will not light up because the  circuit is broken.

A circuit in which energy can freely flow.

• Closed Circuit
• Free Circuit
• Open Circuit
• Energy Circuit

Choose the corrrect sentence.

• This circuit will work because it is an open circuit
• This circuit will work because it is a closed circuit.
• This circuit will NOT work because it is an open circuit.
• This circuit will NOT work because it is a closed circuit.

Choose the correct sentence.

• This circuit will work because it is an open circuit.
• This circuit will work because it is a closed circuit.
• This circuit will NOT work because it is an open circuit.
• This circuit will NOT work because it is a closed circuit.

Would would best complete this circuit?

• A wire
• A switch
• A battery
• A light bulb
