The diagram shows the process of generating electrical power using water in a hydro-electric system. Overall, there are three main stages in this process, starting with the evaporation of seawater, followed by the generation and distribution of electricity to various locations such as homes, schools, and hospitals.
The process begins when the sun heats the water in the sea, which causes it to evaporate and form clouds. After that, the clouds produce rain that falls on the land. Some of this rainwater is collected in a reservoir behind a dam. The dam has a valve that can be opened to let water flow through. When the water flows, it moves a turbine, and this movement helps to generate electricity.
In the next stage, the electricity goes through high-voltage cables to a transformer station. There, the voltage is adjusted to the correct level. In the final step, the electricity is sent through underground cables to different places such as hospitals, schools, and homes. This is how water is used to produce and deliver electricity.
