Closed Circuits

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

• parallel circuit
• series circuit
• closed circuit
• short circuit

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

• not related to circuits

• An incomplete circuit that does not allow electricity to flow

A open circuit allows charges to flow. 

• True 
• False

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.
