A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy transformations are taking place?

• chemical → light → electrical
• mechanical → sound → light
• thermal → solar → electrical
• electrical → thermal → light

When water falls through a dam and turns a turbine connected to a generator, electricity is produced. This electricity is often used to light our homes and offices. Which of the following shows the energy transformations that occurs?

• electrical → light → mechanical
• chemical → mechanical → electrical
• mechanical → chemical → light
• mechanical → electrical → light
