This image represents what type of circuit?

• open

• closed

• series

• parallel

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

A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?

Students constructed a circuit using different-colored lightbulbs. What will happen if Switch 3 is closed and the other switches are left open?

• Only the white bulb will operate

• None of the bulbs will operate

• Only the white and yellow bulbs will operate
