Energy is the basic necesscity for the economic development of a country. Many functions necessary to present day living grind to halt when the supply of energy stops. It is practically impossible to estimate the actual magnitude of the part that energy has played in building up of present day civilization. The availability of huge amount of energy in the modern times has resulted in the shorter working day, higher agricultural and industrial production, a healthier and more balanced diet and better transportation facilities.

As a matter of fact, there is close relationship between the energy used per person and his standard of living. The greater the per capita consumption of energy in a country, the higher is the standard of living of its people.

Energy exists in different forms in nature but the most important form is electrical energy.

The modern society is so much dependent upon the use of electrical energy that it has become a part of parcel of our life.

In this space we shall focus our attention on various aspects of electrical and electronics engineering.

So let us gather together and discuss about the thing that we cannot see i.e Electricity (atleast I had never seen electricity before I don't know about others) because nothing is more thriller than current, isn't it ?
