A hydroelectric generator requires two things to produce power; water and head. Water is obviously needed to spin the turbine, and head is the difference in altitude between the surface of the water in the reservoir above the generator and the water turbine at the generator.

What two countries have more than half of their power from hydroelectric power?
Norway is one I guess Iceland is another.
The power angle of a synchronous motor is affected by what two things?
the excitation voltage applied the power input to the prime mover
Creating new things to solve problems and improve life depends on the close interaction of which two fields?
conservation and research
Why does the electrical resistivity of a conductor does not depend on its dimensions?
resistivity and resistance are two diff. things...........resistance depends on length and thickness resisitivity too depends on the area and length resistivity=resistance*area/length
What is hydroelectricity used for?
The same things all other electricity is used for. Home use ... lighting, heating, etc. Business/ industry uses, electrolysis of (purification of) metal ores, welding, lighting, heating, computers, anything you can think of.Precisely the same as the uses of electricity.Same as for any electricity. The hydro bit is to do with how it is made. After that it is just like any other electricity.Hydroelectric energy is electricity produced from the power of water being pulled by gravity through turbines. It is just electricity. It is no different from electricity produced by any other means.It is used just like normal energy, to power homes, industries, streetlamps, the computer you're using etc.Use of flowing water to create electricity is called hydroelectric energy. The most common type of hydroelectric plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a pipe and into a turbine, which spins to drive a generator, producing electricity.Pumped storage plants use a two-reservoir system, pumping water from a river or a reservoir to a higher reservoir when electricity prices are low during the night. When the value of electricity on the grid is higher during the day, water is released from the upper reservoir, spinning the turbines to produce electricity.it is used to light our homes ,industries etcYou use hydroelectric energy to get electricity from moving water. the hydroelectric power plant is mostly located at a river that's on a slope. then, they make a dam, which is the power plant.powering lights houses and other things.In other words hydroelectric stuff powers electricityIn most countries it just goes into the electricity distribution network, so it is not possible to say. There may be some isolated places that only have hydro power, but in any case it is used for all the usual things we use electricity forit it used to power many places like homes and businesses.Hydroelectric power is a specific type of electrical power that is generated through using water (typically falling water) to turn a turbine that spins turbines that generate electricity. The electricity is used in the same fashion as all other electricity generated from burning fossil fuels or from solar panels is used - to power electric appliances from refrigerators to cell phones.
What project helped farmers and create jobs by reactivatin a hydroelectric power?
The thing you're talking about are two different things;for farmers, the AAA or Agriculture Adjustment Act helped them and the reactivating a hydroelectric power was the TVA or the Tennessee Valley Authority.
What are two sources of energy from moving water?
Water power and hydroelectric power.
What are two examples of renewable?
Hydroelectric power and solar energy.
What are two differnet sources of energy that can be converted by a generator?
They are wind power and Hydroelectric power
What are two alternatives to using fossil fuels for power?
Two alternatives are Hydroelectric and Geothermal.
What two countries have more than half of their power from hydroelectric power?
Norway is one I guess Iceland is another.
Why Is hydroelectric power better than wind?
Well there both two power sources that are renueable.... There both good......
What are two energy resources which are not fuels and which are used to generate electricity?
Wind power, hydroelectric power, solar power, tidal power, nuclear power, geothermal power.
What Two energy resources which are not burnt fuels and which are used to generate electricity?
Wind power, hydroelectric power, solar power, tidal power, nuclear power, geothermal power.
What are two good things about hydroelectric energy?
Its basically free (rain, or rain run-off ) if your lucky enough to live close to a river or mountains that have a dam that can convert it to hydro-electric power.
What are the other two ways of saying water power?
One way to say water power is hydroelectric power. Another way to say it is just hydroelectricity.
A river's power to erode depends on?
There are three things a river's power to erode depends on that includes the slope of the river. The other two things are the volume of flow and the shape of its stream bed.
