Similarly, with simple arrangements, the speed of electric motors can be easily varied over the desired range. It can be easily transported from one place to another with the help of conductors. Thus it is overall economical to use this form of energy for domestic, commercial and industrial purposes.
Therefore, its use ensures cleanliness and healthy conditions. The electrical energy can be transmitted conveniently and efficiently from the centres of generation to the consumers with the help of overhead conductors known as transmission lines. Aneel Kumar Akhani on September 22, Rating: 5.
The availability of huge amount of energy in the modern times has resulted in a 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 a 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 the electrical energy. The modern society is so much dependent upon the use of electrical energy that it has become a part and parcel of our life. In this chapter, we shall focus our attention on the general aspects of electrical energy.
Importance of Electrical Energy:. Energy may be needed as heat, as light, as motive power etc. The present-day advancement in science and technology has made it possible to convert electrical energy into any desired form.
This has given electrical energy a place of pride in the modern world. The survival of industrial undertakings and our social structures depends primarily upon low cost and uninterrupted supply of energy.
