Hydroelectric-dam Virtual Field trip

Hydroelectric-dams create Electricity, they do this by using the power of water. Hydroelectricity is created by capturing the energy of falling water which generates electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy. There are three major parts to a Hydroelectric-dam, The Dam itself, the Generator, Turbine, and Transmission lines, shown below.

The dam raises the water level allowing the water to drop and create energy. The Turbine at the bottom of the slope is turned by the falling water, this turns the Generator. The Generator produces the Energy, and sends this energy through the Transmission Lines.

Hydro Dam

The Dam, the most important part of the entire plant, without it, nothing in the plant will work. The Dam raises the water level allowing water to flow / fall through. it is thanks to this Kinetic energy that the dam can generate power.

A turbine not yet installed.

The turbine is the driving force of the plant, it turns the generator and makes energy. Because the Turbine is underwater, deep in the plant, for learning purposes we are looking at a new, not installed turbine. As you can see, the water goes in one end, and like a conch shell, swirls down toward the center, moving the arrows.

Generator

The Generator, turned by the turbines below produces power as it spins around.

The generator is based on the principle of "electromagnetic induction" discovered in 1831 by Michael Faraday, a British scientist. Faraday discovered that if an electric conductor, like a copper wire, is moved through a magnetic field, electric current will flow (be induced) in the conductor. So the mechanical energy of the moving wire is converted into the electric energy of the current that flows in the wire.

Power-lines.

Lastly, is the power transport. Power-lines take the energy from the Hydroelectric-Dam, and transfer it to Schools, business's, and homes.
