electrical -> light -> chemical electrical -> chemical -> light chemical -> light -> electrical chemical -> electrical -> light
I gave my students this multiple choice question: Which sequence of energy transformations occurs after a battery-operated flashlight is turned on?

Only one answer is correct among these 4 choices:
- electrical -> light -> chemical
- electrical -> chemical -> light
- chemical -> light -> electrical
- chemical -> electrical -> light

Could you tell me which one is correct?

chemical -> electrical -> light
