Electricity

It is impossible to imagine our civilization without electricity: economic and social progress will be turned to the past and our daily lives completely transformed.

Electrical power has become universal. Thousands of applica­tions of electricity such as lighting, electrochemistry and electro­metallurgy are longstanding and unquestionable.

With the appearance of the electrical motor, power cables re­placed transmission shafts, gear wheels, belts and pulleys1 in the 19-th century workshops. And in the home a whole range of various time and labour saving appliances2 have become a part of our ev­eryday lives.

Other devices are based on 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 had been used before.

Electric lighting came into wide use at the end of the last cen­tury with the development of the electric lamp by Thomas Edison. Then the transformer was invented, the first electric lines and net­works were set up, dynamos and induction motors3 were designed.

Since the beginning of the 20th century the successful develop­ment of electricity has begun throughout the industrial world. The consumption of electricity has doubled every ten years.

Today consumption of electricity per capita4 is an indicator of the state of development and economic health 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, easily-regulated and generates no by-products5. 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. Truly6 electricity provides mankind with the energy of the future.

Notes to the Text

  1. transmission shafts, gear wheels, belts and pulleys — транс­миссионные валы, зубчатые колеса, ремни и блоки

  2. time and labour saving appliances — электроприборы, эко­номящие время и труд

  3. induction motors — индукционные моторы

  4. per capita — на человека; на душу населения

  5. by-products — побочные продукты

  6. truly — поистине

II. Answer the questions:

1. What is this text about?

2. What industrial applications of electricity do you know?

3. What home applications of electricity do you know?

4. Where was the generator developed?

5. Who in­vented the electric lamp?

6. Do you know who invented the dy­namo?

7. Can you imagine our life without electricity? Why?

  1. Electricity

  2. The applications of electricity in the home and industry …

  3. Electricity was used for the first time …

  4. The generator, a new source of electricity …
