Answer

1. Both convert mechanical energy to electrical energy, but differ in scale, efficiency, and capacity. ### 2. Use in emergencies, education, and sustainable device design. ### 3. Possible new questions: - How does crank speed affect output? - Which generator type is most efficient? - How long can stored power last in a small generator? Explanation 1. Compare hand-generated flashlight and power plant A hand-generated flashlight produces electricity manually with mechanical energy from cranking, while a power plant uses large-scale energy sources (fossil fuels, nuclear, renewable) to generate electricity for widespread distribution. Both convert mechanical energy to electrical energy but differ in scale, efficiency, and purpose. 2. Identify possible applications of learned information This knowledge can be applied in emergencies (off-grid power), teaching energy conversion, or designing small-scale sustainable devices. 3. Brainstorm new investigation questions Examples: How does crank speed affect flashlight brightness? Which design generates the most electricity per turn? How efficient is each step in energy conversion?
