This circuit has a battery, buzzer, and switch.
When the switch is closed the buzzer will sound because -

• the switch gives energy to the battery
• the buzzer is made of special plastic
• the wires are cooled by the surrounding air
• electricity can flow in a complete path

When electricity flows in a circuit, it can produce all of the following forms of energy EXCEPT,

• solar
• light
• thermal
• sound

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
