DOL: 9.18 (TYPES OF CIRCUITS)

Students constructed a circuit using different-colored lightbulbs. What will happen if Switch 2 is closed and the other switches are left open?

• Only the blue bulb will light up.

• None of the bulbs will be light up

• Only the white and yellow bulbs will light up.

• Only the blue and white bulbs will light up.

In some circuits that are used for decorating, one burned-out light bulb will prevent all the other light bulbs from lighting. In other circuits, one burned-out light bulb will have no effect on the light bulbs. In which of these circuits will the other light bulbs still light even if one bulb is burned out?

What is the main difference between series and parallel circuits?

• Series circuits have multiple paths; parallel circuits have one path.

• Series circuits can handle more current than parallel circuits.

• Series circuits have one path; parallel circuits have multiple paths.

• Series circuits are used in all electrical devices; parallel circuits are not.

A fifth-grade class constructed this circuit. Which of these objects most likely made the light glow when connected to points X and Y?

• plastic straw

• cotton string

• aluminum foil

• rubber eraser

Answer explanation

Aluminum foil is a good conductor of electricity, allowing current to flow and making the light glow. In contrast, a plastic straw, cotton string, and rubber eraser are insulators and would not complete the circuit.
