Open or Closed Circuits

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

• closed circuit

• open circuit

• 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 battery would loose energy

The on switch shows

• An open circuit where electricity can flow

• A closed circuit that is also called complete
