Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity
Explanation:
Hydroelectric power is generated from free falling water through a river channel.
The flow of water at a high speed creates water current and the kinetic energy of the water movement spins turbine attached with a generator. This produces a rotating energy which spins the generator and the coil inside.
The magnetic spinning of coiled wire inside the generator produces electric current which is then stored and transmitted through electric power grid lines to supply electric current.
