In a battery-powered flashlight, the primary energy transformations that take place can be identified as follows:
1. **Chemical Energy to Electrical Energy**: The battery stores chemical energy, which is converted into electrical energy when the flashlight is turned on.
2. **Electrical Energy to Radiant Energy**: The electrical energy travels through the wires to the light bulb, where it is converted into radiant energy (light).
3. **(Optional) Additional mention**: While not a primary transformation in this context, some theoretical conversions such as energy lost as heat could be considered, but are not explicitly asked in your query.
So the relevant energy transformations occurring in the flashlight are:
- Chemical Energy (from the battery) → Electrical Energy (through the wires) → Radiant Energy (from the light bulb).
