It is impossible to imagine our civilization without electricity: economic and social progress will go back to the past which will completely transform our daily lives. Electrical power has become universal. Thousands of applications of electricity such as lightning, electrochemistry and electrometallurgy are longstandin g and unquestionable.

With the appearance of the electrical motor power cables replaced transmission shafts, gear wheels, belts and pulleys in the 19^th century workshops. And in the home a large range of various time and labour saving appliances have become a part of our everyday life. Other devices are based on the specific properties of electricity: electrostatics in the case of photocopying machine and electromagnetism in the case of radar and television. These applications have made electricity most widely used.

The first industrial application was in the silver workshops in Paris. The generator – a new compact source of electricity- was also developed there. The generator replaced the batteries and other devices that a man had used before. Electric lightning came into wide use at the end of the last century after Thomas Edison had developed the electric lamp. Then the transformer was invented, the first electric lines and networks were set up, dynamos and induction motors were designed. In the beginning of the 20^th century the successful development of electricity began throughout the industrial world. The consumption of electricity has doubled every 10 years.

Today consumption of electricity per capita is an indicator of the state of development and economic state of a nation. Electricity has replaced other sources of energy as it has been realized that it offers improved service and reduced cost. One of the greatest advantages of electricity is that it is clean, easy-regulated and generates no by-products. Applications of electricity now cover all fields of human activity from house washing machines to the latest laser devices. Electricity is the efficient source of some of the most recent technological advances such as the laser and electron beams. Truly electricity provides mankind with the energy of the future.
