Open Closed Circuit

What is the power source in this circuit?

• Lightbulb

• Switch

• Wires

• Battery

What is a switch's function in a circuit?

• to make the current hotter or colder

• turn on and off the flow of current

• the pathway that current flows

• to add more power to the 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

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.

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

• closed circuit

• open circuit

The on switch shows

• An open circuit where electricity can flow

• A closed circuit that is also called complete

Would would best complete this circuit?

• A wire

• A switch

• A battery

• A light bulb

A continuous path of conductors that allows electricity to pass through easily is called a(n)...

• Closed circuit

• Double circuit

• Open circuit

• Electric current

A student began building a circuit to light a bulb.  What else does the student need to produce light?

• a battery that has energy

• a wire that is insulated

• a switch that is open

• another bulb of the same size
