Transformer is a statics device which is used for transfer the electrical power from one circuit to another circuit without change in frequency and it’s work on the fraday’s law of mutal induction .   1.  According to construction there are two types of transformer- core type and shell type.      2. Generally there are five types of transformer according to services- instrument transformer , step up transformer and step down transformer, single phase and three phase transformer, Power transformer, Distribution transformer.   Core type- In the core type transformer on the two core limb. it has only  one magnetic circuited or magnetic flux path . It is used for lower voltage level applications. It has less mechanical protection to coil . Here losses is more than the shell type transformer. maintenance and repairing of this transformer is very simple. It has two limbs . natural cooling is provided since more surface is exposes to at...

Renewable energy /Non renewable energy / Global Impact of Renewable Resources. Renewable energy     A  renewable resource  is a  natural resource  which usage and consumption again and again(in one form to another form) ,it's energy not run out, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. Renewable resources are a part of Earth's natural environment and the largest components of its  ecosphere . A positive life cycle assessment is a key indicator of a resource's sustainability.  A renewable resource, essentially, has an endless supply such as solar energy, wind energy, and geothermal pressure. Other resources are considered renewable even though some time or effort must go into their renewal (e.g., wood, oxygen, leather, and fish). Most precious metals are renewable also. Although precious metals are not naturally replaced, they can be recycled because they are no...
