What does electrical engineering study?


The science called "Electrical Engineering" studies everything related to electrical energy, namely its production, distribution, use and transformation. Electrical engineering separated from physics into an independent science only at the end of the 19th century.

Electrical engineering includes such sciences as electronics, electric power, control systems, telecommunications and signal processing. The difference between electrical engineering and electronics is that the first deals with the study of the transmission of electricity, and the second – information.

The advantages of electrical energy over other types of energy explains the widespread use of electrical engineering as a science. These advantages include: ease of conversion to another type of energy, transmission over any distance, "separation" of energy, as well as control of electrical appliances.

Electrical engineering, as a branch of industry, widely uses electrical energy in the automation of production processes. Thanks to the development of electrical engineering, almost all technological processes in industry were automated.

The areas where electrical energy is used are constantly expanding, which contributes to the deep introduction of electrical engineering into many branches of agriculture and industry. Moreover, without the use of electrical energy, a normal life is almost impossible.

The only disadvantage of electricity is the inability to store its reserves for a long time. Batteries and galvanic cells are able to contain energy that is suitable only for the operation of low-power devices. In this regard, electricity is produced in the amount and when it is needed by the consumer. Therefore, power generation companies are constantly in need of specialists with a certain knowledge of electrical engineering.
