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

Energy Sources

ENERGY RESOURCES:           Energy sources can be classified into two types. They are renewable and non-renewable sources of energy. Non renewable:          Non renewable resources, such as fossil fuels and nuclear material, are removed from the earth and can be depleted. These resources have been the most used type of energy in the modern era. i) Coal:        Coal is a non renewable fossil fuel produced worldwide. It is formed when millions of years of pressure and heat turn the remains of prehistoric forests and swamps into coal. Coal is taken out of the earth either by deep mining(tunnelling underground) or strip mining(digging out layers of earth). It exists in different grades or qualities.        Coal is used predominantly to produce electricity and to provide fuel for industries that require large amounts of heat. Production of steel, cement and paper all related on this industry. Coal traditionally has been used for heating many homes and businesses. i

Solar Power Advantages and Disadvantages

Solar Power:                   Solar power is the the conversion of the energy from the sun to usable electricity. The most common source of solar power utilizes photovoltaic cells to convert sunlight into electricity. Photovoltaics utilize a semi-conductor to absorb the radiation from the sun, when the semi-conductor abosrbs this radiation it emits electrons, which are harnessed as electricity.  Advantages of Solar:             Solar energy is a resource that is not only sustainable for energy consumption, it is indefinitely renewable (at least until the sun runs out in billions of years). Solar power can be used to generate electricity, it is also used in relatively simple technology to heat water (solar water heaters). The use of skylights in home construction can also greatly reduce energy expenditure required to light rooms in a homes interior during the day.                 Solar panels also require little maintenance.
