How is electicity manufactured?

Answer 1

As everybody know that electricity is a form of energy.The basic principle is that energy can be converted from one form to another,but it cannot be manufactured. There are many ways to generateelectricity. The various sources are 1.solar 2.wind 3.nuclear power, 4.fossil fuels and coal. The first two are renewable sources and the later are non-renewable sources. Solar energy: Here the heat energy from sun is used.this heat is used in genarating steam which in turn drives turbine to produce electricity. Wind energy:

Here the heavy wind turns the huge wings of the wind mill which inturn turns the armature placed between magnetic field.Thus change in magnetic flux generates electricity. Nuclear power, fossil fuels and coal: In both the cases the fuel used to generate heat varies.But the principle to produce electricity is same. In nuclear power plant,due to fission reaction of U235,heat is generated. In later case ,fossil or coal is burnt to generate heat. The heat generated is used in steam generator to produce steam which in turn runs turbines to generate electricity.
