When the switch is turned on in a simple circuit containing a battery, a switch, and a bell, the energy transformation that occurs is from electrical energy to mechanical energy.
Here's how it works:
- The battery provides electrical energy when the switch is closed (turned on).
- This electrical energy flows through the circuit and energizes the bell.
- The bell then converts this electrical energy into mechanical energy, producing sound as it rings.
So, the overall energy transformation is electrical energy → mechanical energy (and sound energy, as a byproduct).
