A student constructs the circuit shown for a science demonstration. With the switches in these positions, which lights are on? (a)  

• All the lights

• 1 and 2 only

• 3 and 4 only

• none of the lights

In a solid, the moving electric charges are called​ (a)   .​

• electrons

• protons

• neutrons

Match the following

• circuit that has multiple pathways

• Insulator

• a circuit with only one path

• Current

• material that stops or slows energy

• Series Circuit

• flow of energy

• Parallel Circuit

• material that allows energy to flow

• Conductor

Match the following

• Chemicals that react and give power. Example: batteries

• Closed Circuit

• A device that allows a circuit to be open or closed.

• Switch

• A completed path that allows electricity to flow through it.

• Open Circuit

• A path that is broken and won't allow electricity to flow through it.

• Power Source

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 type of circuit is represented by the diagram?

• closed

• series

• open

• parallel

If bulb 1 burns out, what will occur?

• bulbs 2 and 3 will go out

• bulbs 2 and 3 receive more volts

• bulbs 2 and 3 will stay lit

• nothing will happen
