Question

A simple circuit is wired with a battery, a switch, a bell. When the switch is turned on, what energy transformation will occur?

Answer 1

In a simple circuit containing a battery, a switch, and a bell, when the switch is turned on, the following energy transformation occurs:

1. **Chemical Energy to Electrical Energy**: The battery converts its stored chemical energy into electrical energy.
2. **Electrical Energy to Sound Energy**: The electrical energy flows through the circuit and powers the bell, which then transforms that electrical energy into sound energy (producing the sound of the bell ringing).

So, the overall energy transformation can be summarized as: **Chemical Energy (from the battery) → Electrical Energy → Sound Energy (from the bell)**.
