Question

what energy transformation is occurring in the diagram below?
electrical to chemical to electromagnetic (em)
chemical to electrical to electromagnetic (em)
thermal to electromagnetic (em) to electrical
nuclear to chemical to thermal

Explanation:

In a flashlight (implied by battery + flashlight = light bulb), the battery has chemical energy. The battery converts chemical energy to electrical energy to power the circuit. Then, the light bulb (or flashlight) converts electrical energy to electromagnetic (light) energy. So the energy transformation is Chemical (battery) → Electrical → Electromagnetic (light), matching option B.

Answer:

B. Chemical to Electrical to Electromagnetic (EM)
