Questions & Step-by-Step Solutions

In hydroelectric power generation, what is the role of the dam?
  • Step 1: A dam is built across a river to block the flow of water.
  • Step 2: When the dam blocks the water, it creates a large area of stored water called a reservoir.
  • Step 3: The stored water in the reservoir can be released when needed.
  • Step 4: When the water is released, it flows down through pipes to turbines.
  • Step 5: The flowing water turns the turbines, which are connected to generators.
  • Step 6: The generators convert the movement of the turbines into electricity.
