A hydro dam works by taking the energy of water flow and converting it into an electric voltage. The water is regulated through a series of water turbines. The water flows through the turbine, pushing the turbine blades causing a rotation to a shaft. The shaft is then attached to an electrical generator. Inside the electrical generator, magnets are rotated around wire coil inductors which cause a voltage.

The word 'hydro' means water. When water is stored in a reservoir by construction dam, the stored water will have gravitational potential energy. When water is allowed to flow down this PE is changed into kinetic energy. This KE will make the wheels of a turbine to rotate. This mechanical energy ie rotational energy is changed into electrical energy with the help of magnetic field. This phenomenon is known as electromagnetic induction, first found by Michael Faraday. This is how hydro power is changed into electrical power.

The energy in moving (falling) water, is supplied by gravity, and the moving water has kinetic energy. This mechanical energy is applied to turbine blades, and the turbines turn electric generators to generate electricity.

Hydro power is generated by using kinetic energy from flowing water to turn turbines in generators.
Turbine is moved with flow of water and this is coupled with generator to produce electricity

Hydro- means water, so hydroelectric is electricity generated by water! See the links for a picture diagram that helps to visualize it.
Dam do not generate electricity
1. Dams store water
2. Under Dams PENSTOCKS are arranged
3.by penstocks water is release by a nozzle to turbines
4.Then turbines rotates and it connected to generators
5. Generators rotate and generate electricity
A:Water passes through a turbine that makes it spin, and this energy is converted to electricity.Dams generate electricity by causing water to flow through devices called a turbine generators.
You can think of the turbine as a water wheel. The water flows over the water wheel making it turn. The water wheel is connected to a large coil of wire which turns in a magnetic field. When wire moves in a magnetic field it generates electricity.
The dam itself can not but by using hydroelectricity it can.There are propellors inside the dam which are turned by flowing water and the faster the water flows the more energy they produce

How are hydroelectric power stations built?
Firstly, the topographer makes a detailed study of the topography on the local, in which the hydroelectric power plant will be built. Then on an appropriate place the terrain is lowered to form the waterfall which will move the turbines that will generate electricity. The river is blocked to form a huge dam and it has a channel to make the water fall from the top of the dam. Many stages to be followed until the turbines begin to generate electricity.
What is a dam How is it useful to us?
A dam is used to make an artificial lake in a river which can be used to generate hydroelectric power or as a reservoir.
Can you put the word hydroelectric in a sentence?
In hydroelectric power station we use the potential energy of water to generate electricity.
Where does hydropower come from?
Dams such as Hoover Dam or the dams of the Niagra River generate hydroelectric power.
What is the purpose of a hydro electric dam?
to generate electricity by utilizing energy of falling water
Magnets spinning inside a hydroelectric dam generate what?
electricity
Why is the hydroelectric dam used to provide power for homes in Singapore?
Singapore does not use hydroelectric dams to generate electricity.
What is hdroeletricity?
Hydroelectric power is generated by water passing through the blades of a turbine to generate electricity. Typically this is done at a waterfall or dam.
What is the definiton of hydroelectric dam?
A hydroelectric dam uses the force of flowing water to drive turbines which generate electric power.
Do we use more freshwater in our homes to provide us electricity?
No. Water can be used in a hydroelectric dam to generate electricity, but this does not make us use more or less water in our homes.
How does the hydroelectric generating system work?
Take for example, a dam. Water flows through the gates (when opened) of the dam and turn turbines. Inside these turbines are coils of copper usually that generate electricity.
What are applications of hydroelectric genrator?
oh boy,,, How about the hydroelectric generators and the base of a dam ?? Electricity for you and me ... ?
What are the advantages and of generating electricity using a hydroelectric dam?
TVA

What is the definiton of dam?
A hydroelectric dam uses the force of flowing water to drive turbines which generate electric power.
How does the Hoover Dam work?
The hoover dam works by spouting water out of penstocks and into a man-made river, which then enters the dam and the moving water turns the turbines of the generator, which produces the energy we need to power things.
What type of energy use at home?
Hydroelectric power (from a dam), nuclear energy, solar power and wind power generate electricity. Natural gas is used for heating. Solar (the sun) can produce heat and electricity.
