A simple circuit is wired with a battery, a switch, and a bell.
When the switch is turned on, what energy transformations will occur?
(1 point)
Responses
The battery’s chemical energy transforms to sound energy, which the wire transfers to the bell.
The battery’s chemical energy transforms to sound energy, which the wire transfers to the bell.
The switch transforms electrical energy to chemical energy, which the bell then transforms to sound energy.

The switch’s electrical energy transforms to sound energy, which the wire transfers to the bell.
The correct response is:
The battery’s chemical energy transforms to electrical energy, which the bell then transforms to sound energy.
In this process, the chemical energy stored in the battery is converted into electrical energy when the circuit is completed by the switch, and then the bell converts that electrical energy into sound energy.
