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, andelectric power distribution and use. Subsequently, broadcasting andrecording media made electronics part of daily life. The invention of thetransistor, and later the integrated circuit, brought down the cost of electronics to the point 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,radio-frequency engineering, signal processing, instrumentation, andmicroelectronics. The subject ofelectronic 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 adegree in electrical engineering or electronic engineering. Practicing engineers may have professional certification and be members of aprofessional body. Such bodies include the Institute of Electrical and Electronics Engineers (IEEE) and theInstitution of Engineering and Technology (professional society)(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 aproject 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 .
History :-
Electricity has been a subject of scientific interest since at least the early 17th century. The first electrical engineer was probably William Gilbertwho designed the versorium: a device that detected the presence of statically charged objects. He was also the first to draw a clear distinction between magnetism and static electricity and is credited with establishing the term electricity. Then in 1762 Swedish professor Johan Carl Wilcke invented, and in 1775 Alessandro Voltaimproved, a device (for which Volta coined the name electrophorus) that produced a static electric charge, and by 1800 Volta had developed thevoltaic pile, a forerunner of the electric battery.
Education
Electrical engineers typically possess an academic degree with a major in electrical engineering, electronics engineering, electrical engineering technology, or electrical and electronic engineering.The same fundamental principles are taught in all programs, though emphasis may vary according to title. The length of study for such a degree is usually four or five years and the completed degree may be designated as a Bachelor of Science in Electrical/Electronics Engineering Technology, Bachelor of Engineering, Bachelor of Science,Bachelor of Technology, or Bachelor of Applied Science depending on the university. The bachelor's degreegenerally includes units coveringphysics, mathematics, computer science, project management, and avariety of topics in electrical engineering. Initially such topics cover most, if not all, of the subdisciplines of electrical engineering. At some schools, the students can then choose to emphasize one or more subdisciplines towards the end of their courses of study.
