Electrical engineering is a branch of engineering that basically deals with the study and application of electronics, electricity, and electromagnetic waves. This branch first became a well-known occupation at the end of the 19th century after the invention of the telephone, electric telegraph, and electric power use and distribution. It now has a variety of applications such as computers, electronics, power engineering, biomedical engineering, signal processing, telecommunications, and RF engineering.

Electrical Engineers design power systems

Electrical Engineers design Electronic Systems
Electrical engineering includes electronic engineering. This distinction is only found in the US. Electrical engineering deals with the applications associated with systems like electric power systems, and electrical machines. However, electronic engineering is the study of electronic systems including digital computers, optoelectronics, integrated circuits, communication systems, and radar.
In other words, electrical engineering is usually concentrated on using electricity to transmit electric data or power, while electronic engineering uses electricity to process information. Both of them can overlap, for instance, in the increase of power electronics, and the study of the behavior of large electrical grids under the control of electronics and computers.
Computer engineering is a branch that combines many fields of electrical engineering and computer science required to enhance computer software and hardware. It is necessary for computer engineers to have experience in electronic engineering , software skills, and hardware-software integration instead of only software engineering or electronics. Computer engineering is necessary for many software and hardware aspects of computing, from the design of microprocessors, microcomputers, personal computers, and supercomputers, to simple electronic circuit design. This field of engineering not only concentrates on how computers themselves work, but also how they integrate into the larger image.
Traditional jobs involving computer engineers include writing firmware and software for embedded microcontrollers, fabricating VLSI chips, designing analog detectors, designing operating systems, and designing mixed signal circuit boards. Computer engineers are also involved in robotics research, which depends heavily on using digital systems to control and observe electrical systems like sensors, motors, and communications.
In many universities, computer engineering students are allowed to select in-depth study classes in their junior and senior year, because the full breadth of understanding used in the fabrication and application of computers is beyond the target of an undergraduate degree. Other institutions ask their students to finish one year of general engineering before selecting computer engineering as their primary focus.
Michael Farady formed the foundation of electric motor technology
Electricity has been a hot subject of research since the early 17th century. The first electrical engineer was William Gilbert who fabricated the versorium: an apparatus that sensed the presence of statically charged bodies. He was also the first to draw a clear difference between static electricity and magnetism and is credited with coining the word electricity. In 1775, Alessandro Volta's scientific experimentations designed the electrophorus, a device that generated a static electric charge, and in 1800 Volta developed the voltaic pile, a forerunner of the electric battery.
The invention of the transistor in late 1947 by William B. Shockley opened the door for more smaller devices which led to the development of the integrated circuit in 1958 by Jack Kilby; and independently in 1959, by Robert Noyce. In 1968, Ted Hoff et al at the Intel Corporation invented the first microprocessor, which was the basis of the personal computer. The Intel 4004 was a four-bit processor produced in 1971, but in 1973, the Intel 8080, an eight-bit processor, led to the creation of the first personal computer.
In 1972, the first computer engineering degree in the US was established at Case Western Reserve University. In 2004, there were 170 ABET-accredited computer engineering programs in the US. In Europe, accreditation of computer engineering programs is done by a different agency – part of the EQANIE network. Due to the growth in job requirements for engineers, who can concurrently develop hardware, software and firmware; as well as manage all forms of computer systems used in industry, some tertiary school around the world offer a bachelor's degree generally called computer engineering. Both computer electronic engineering programs include analog and digital circuit design in their curricula. As with most engineering disciplines, having a good background in mathematics and science is necessary for computer engineers.
Specialty Areas
Electrical engineering has many sub-disciplines, the most popular of which are listed below. Although there are electrical engineers who focus exclusively on one of these sub-disciplines, many deal with a combination of them. Sometimes certain fields, such as electronic engineering and computer engineering, are considered separate disciplines in their own right.
Power engineering:
Power engineering deals with the generation, transmission and distribution of electricity, as well as the design of a range of related devices. These include transformers, electric generators, electric motors, high voltage engineering, and power electronics. In many regions of the world, governments maintain an electrical network called a power grid that connects a variety of generators together with users of their energy.
Power plant
Users purchase electrical energy from the grid, avoiding the costly exercise of having to generate their own. Power engineers may work on the design and maintenance of the power grid as well as the power systems that connect to it. Such systems are called on-grid power systems and may supply the grid with additional power, draw power from the grid or do both. Power engineers may also work on systems that do not connect to the grid, called off-grid power systems, which in some cases are preferable to on-grid systems. The future includes Satellite controlled power systems, with feedback in real time to prevent power surges and prevent blackouts.
