Open vs Closed Circuits

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

• parallel circuit
• series circuit
• closed circuit
• short 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

Current is referred to as:

• flow of electricity
• circuits
• flow of electrons
• batteries

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
