THESISThis work is a research analysis. The history of electricity, electrician trade and its background are described here. The aim of the work is to investigate the reasons of this trade emergence and to determine its place in the world of professions and trades and its total necessity nowadays. The object of study is the electrician profession, its features, characteristics and peculiarities. The relevance of research is actual one as to its modern necessity at the world’s technology development and existence. As a result a general conclusion is made concerning to the approaches of research object.

Introduction Everything has its history. We know the definitions, the tools and different types of equipment, installation or outfit, but sometimes we don’t remember or know how it began. In this work I’d like to analyze and show you the history of electricity. It’s an amazing and interesting return to the past to investigate. This article is to show the importance and necessity of my profession of electrician. 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 pulleys in the 19-th century workshops. And in the home a whole range of various time and labour saving appliances 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. So, how it happened to born?

History of electrical engineering development Ancient development Thales of Miletus, an ancient Greek philosopher, writing at around 600 B. C., first described a form of static electricity, noting that rubbing fur on various substances, such as amber, would cause a particular attraction between the two. He noted that the amber buttons could attract light objects such as hair and that if they rubbed the amber for long enough they could even get a spark to jump. His principal occupation was engineering He had a profound influence on other Greek thinkers and therefore on Western history.

17th century developments Electricity remained little more than an intellectual curiosity for millennia. In 1600 the English scientist William Gilbert extended the study of electricity and magnetism, distinguishing the effect from static electricity produced by rubbing amber. He coined the new Latin word  electricus (the Greek word for "amber") This association gave rise to the English words "electric" and "electricity".

18th century developments Francis Hauksbee

In the 18th century Benjamin Franklin conducted extensive research in electricity A succession of sparks jumping from the key to the back of his hand showed that  lightning was indeed electrical in nature

19th century developments Francis Ronalds was the first electrical engineer, who created the first working electric telegraph system in 1816 Michael Faraday - the discoverer of  electromagnetic induction in 1831 and developter of homopolar generator

Faraday’s Laboratory at the Royal Institution

Thomas Edison  built the world's firstlarge-scale electrical supply network.

Thanks to all these inventors we can speak now about the emergence of electrician trade / profession.

Emergence of a profession Expositions and world's fairs became popular places to showcase new inventions involving electricity. The first successful use of electricity at one of these events occurred at the 1889 Paris Exposition Electricians were hired to build and operate these installations.

Nowadays this profession is still one of the most actual and necessary. An electrician installs, repairs and maintains assorted electrical equipment, such as wiring a house for lighting or fixing a broken refrigerator. He must ensurethat appliance is installed correctly and safely. The history of the profession of electricians grew out of the public's desire for such devices. New inventions are appearing every day and make our life easier, warmer and longer. Nothing can work without electricity. Conclusions
