Electrical Engineering is a branch of Engineering that deals with the invention, design, development and commercial applications of electrical and electronics systems, components and devices. There is a wide variety of domains to which it applies. They go from the very small, as in the development of the one-elecron transistor in nanotechnology to the very large power engineering generators and transmission lines and beyond, as in the satellite communication systems that allow for the GPS in your automobile, which, by the way, belong to the domain of astronomical dimensions!
There are several branches in Electrical Engineering. And, as the discipline is in continuous progress and evolution, new branches or sub-branches appear every year or so. Among the most well-known fields of Electrical Engineering we find, for example, Electrical Power Generation and Transmission, Control Systems, Communications, Robotics, Electronics and Nanotechnology, just to name a few. Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use. Subsequently, broadcasting and recording media made electronics part of daily life. The invention of the transistor and, subsequently, the integrated circuit brought down the cost of electronics to the point where they can be used in almost any household object.
Electrical engineering has now subdivided into a wide range of subfields including electronics, digital computers, power engineering,telecommunications, control systems, RF engineering, signal processing, instrumentation, and microelectronics. The subject of electronic engineering is often treated as its own subfield but it intersects with all the other subfields, including the power electronics of power engineering.
Electrical engineers typically hold a degree in electrical engineering or electronic engineering. Practicing engineers may have professional certification and be members of a professional body. Such bodies include the Institute of Electrical and Electronic Engineers (IEEE) and theInstitution of Engineering and Technology (IET).
Electrical engineers work in a very wide range of industries and the skills required are likewise variable. These range from basic circuit theory to the management skills required of project manager. The tools and equipment that an individual engineer may need are similarly variable, ranging from a simple voltmeter to a top end analyzer to sophisticated design and manufacturing software.
