From where comes the electricity of the water dams?

Question

Please tell me from where the electricity comes on the water dams?

Answer 1

Electric power is produced by hydroelectric generators. Please see the website below.

Answer 2

The energy cycle for hydroelectric power begins on our planet. It begins with the waters within our oceans and lakes. Then it moves to the sun, where a great deal of radiant energy is continually pouring outward, warming our planet. The warming of our planet brings us to the third aspect of the formation of this power - that of water vapor filling our atmosphere. This water vapor cools into clouds, which distills water, in form of rain, into lakes and rivers. The fourth part is that of the water running down a river and meeting a dam, where the water is backed up, forcing it to rise in the river. Where there has been a design in the dam for the water to pass by it, there is a turbine placed there, fifth part. The water forced through the turbine is done so by the force of gravity. Because it is necessary to have an energy source in order for work to be performed, it is obvious that the force of gravity is a particular kind of energy, and must have an energy source, part six. The equation for a gravitational field is part of the physics trilogy; E = mc2, m = E/c2, and c2 = E/m. The last is that for a gravitational field, or a field of physical time - they are the same. Notice that the c2 value remains the same in all the equations and is the foundation of each. Energy and mass are variables. It is the c2 value that is the energy that "pulls" the water downward with a particular force through the turbines. The electric power is generated by the breaking of magnetic lines, which forms electrical impulse, known to us a electricity.

Answer 3

If you have ever seen a water mill, of water wheel,

http://images.search.yahoo.com/search/images?p=water+mill&fr=yfp-t-410&toggle=1&cop=&ei=UTF-8

you can see the we are using water and gravity to cause the water to fall onto the wheel and thus make the wheel spin, this mechanical energy can thus be used to do something, in history it was used to run flour grinders, or sowing machines.

Well newer technolgy of today is essentially doing exactly the same thing, jsut most effieciently. The dam backs up water, which creates a lake or resevoir, which amounts to a lot of weight, or pressure. The water wants to fall, and so its given a special path build into the damm so that we can control its fall, and pass it through a turbine. Just like the the water wheel, a turbine has blades, which get pushed as water passes by.

here is a simply drawing

Thus the huge damms we have built are nothing more then water wheels on steroids, but of course the us of a hydroelectric generator which changes the mechanical spining done by teh turbine and transfers it into electrical energy, that we can use in our homes.

Answer 4

The electricity produced using water dams is called "Hydro Electricity" it is the cheapest method to produce electricity. Because it uses natural resource and it will be least polluting process to generate electricity. In simple words water is coming with force in a tube and rotates the turbine ( like wheel ) which is connected to electrical machines ( Generator) . there are coils of copper wire which cuts the magnetic field , which generates the ion movement in the wire which is then distributed through network of wires ...... This was a very layman terms explanation ... detail explanations are available in many site some of which are given below ....

Answer 5

Water stored in dams has potential energy associted with it.
PE=mass*Acceleration due to gravity*Head
Large mass of water and considerable Head at which it is stored is exploited to generate power. By controlled release of water which is made to turn the turbine generates Hydro-electric power.

Answer 6

i thnk your asking how is electricity produced from water dams? a dam is built to store a large amount of water behind its walls and this helps to build up pressurebehind the walls, the water is then passed through turbines which turn like a dynamo on a bike to produce an electric current which is then distrubited to the electricity network. you should try < http://science.howstuffworks.com/hydropower-plant.htm > to see how it works

Answer 7

It relies upon on the variety you define "keep." Water flows via a dam to spin a turbine which, in turn, generates electricity. As suggested in different posts, the quantity of water flowing via to the different facet is controlled based upon the quantity of electricity the means business enterprise needs to generate. If greater electricity is mandatory, greater water passes via to spin the turbines speedier. If much less electricity is used, much less water passes via to spin the turbines slower. in case you want the water to circulate greater slowly, and that's your definition of "keep" then turning the lights fixtures off "saves" water. in spite of if, the water flows via to the different facet of the dam at one time or yet another. because of the fact no water is extremely "used," no water is extremely "stored." Does that make experience?

Answer 8

because they move a Pelton Turbine that moves a generator that produces Electricity by magnetic means.
