What Is Transformer

Image
The reason for transforming the voltage to a much higher level is that higher distribution voltages implies lower currents for the same power and therefore lower I 2 R losses along the networked grid of cables. These higher AC transmission voltages and currents can then be reduced to a much lower, safer and usable voltage level where it can be used to supply electrical equipment in our homes and workplaces, and all this is possible thanks to the basic  Voltage Transformer . The  Voltage Transformer  can be thought of as an electrical component rather than an electronic component. A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works on the principle of Faraday’s law of induction by converting electrical energy from one value to another. The transformer does this by linking together two or more electrical circuits using a common oscillating magnetic circuit which is produced by the transformer itself. A

Hydro electricity tracking

Hydro electricity tracking:

A generating station which utilities the potential energy of water at a high level for the generation of electrical energy is known as a hydro-electric power station.







Hydro-electric power stations are generally located in hilly areas where dams can be built conveniently and large water reservoirs can be obtained.  In a hydro-electric power station, water head is created by constructing a dam across a river or lake.  From the dam, water is led to a water turbine. The water turbine captures the energy in the falling water and changes the hydraulic energy into mechanical energy at the turbine shaft.  The turbine drives the alternator which converts mechanical energy into electrical energy.  Hydro-electric power stations are becoming very popular because the reserves of fuels and oil are depleting day by day  They have the added importance for flood control, storage of water for irrigation purposes.

Renewable Resources

Renewable Resources: Renewable resources   are resources that are replenished by the environment over relatively short periods of time. This type of resource is much more desirable to use because often a resource renews so fast that it will have regenerated by the time you've used it up. Think of this like the ice cube maker in your refrigerator. As you take some ice out, more ice gets made. If you take a lot of ice out, it takes a little more time to refill the bin but not a very long time at all. Even if you completely emptied the entire ice cube bin, it would probably only take a few hours to 'renew' and refill that ice bin for you. Renewable resources in the natural environment work the same way. Solar energy is one such resource because the sun shines all the time. Imagine trying to harness all of the sun's energy before it ran out! Wind energy is another renewable resource. You can't stop the wind from blowing any more than you can stop the sun fro

Wave Power

Image
Wave Power: Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. To date there are only a handful of experimental wave generator plants in operation around the world. The articles on this page explore the world of wave energy and its possible applications.

Working of Solar Panel

Image
Working of Solar Panel: The solar cells on the calculation and satellites are also called photovoltaic (PVC) cells, Which as the name implies (photo meaning light and voltaic meaning electricity), convert sunlight directly into the electricity. A module is a group of cells connected electrically and packaged into a frame (more commonly known as solar panel), which can then be grouped into large solar arrays. Photovoltaic cells are made of special materials called semiconductors such as silicon, which is currently used most commonly. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely.    PV cells also have one or more electric field that acts to force electrons freed by light absorption to flow in
