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 on switch shows

• An open circuit where electricity can flow

• A closed circuit that is also called complete

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
