Forms of Energy Transformations in Electric Circuits

A battery is attached to a buzzer with wire as shown. The buzzer will make noise only when -

• another wire connects the buzzer to the battery

• the battery is replaced with a stronger one

• switch that can open and close is added

• the wire is replaced with a longer one

A student attached the parts as shown here and the bulb did not light. The most likely reason the bulb does not light is because -

• batteries can’t provide electric energy

• the flow of electricity can’t make a bulb light

• the switch must be open for electricity to flow

• yarn does not conduct electricity

Jerry constructed a circuit.
When the switch is closed, the circuit -

• produces light.

• produces motion.

• produces sound

• does nothing at all

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

A class prepared some electrical circuits using battery, connecting wires, and three light bulbs. Which of these circuits can make the three bulbs light?

• A

• B

• C

• D
