Description


What is Electrical Engineering
  • An Electrical Engineering is a professionaly engineering discipline that generally deals with the study and application of electricity, electronics, and electromagnetism. 
  • This Electrical Engineering  field first became an identifiable occupation in the later half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use. 

  • After than Subsequently, broadcasting and recording media made electronics part of daily life. 


How its a discovered?? 
  • The invention in Electrical field like the transistor, and later the integrated circuit, brought down the cost of electronics to the point they can be used in almost any household object.
  • An Electrical Engineering has now subdivided into a wide range of subfields including electronics, digital computers, computer engineering, power engineering, telecommunications, control systems, radio-frequency engineering, signal processing, instrumentation, and microelectronics.

  •  Many of these Electrical subdisciplines overlap and also overlap with other engineering branches, spanning a huge number of specializations such as hardware engineering, power electronics, electromagnetics & waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics, electrical materials science, and much more.
  • An Electrical Engineers typically hold a degree in electrical engineering or Electronic Engineering. 
  • An Electrical Enginnering the Practicing engineers may have professional certification and be members of a professional body. Such bodies include the Institute of Electrical and Electronics Engineers (IEEE) and the Institution of Engineering and Technology (IET) (formerly the IEE).
  • An Electrical Engineers work in a very wide range of industries and the skills required are likewise variable.
  • In Electrical Engineering 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.

History 
  • An Electricity has been a subject of scientific interest since at least the early 17th century.
  •  William Gilbert was a prominent early electrical scientist, who was the first to draw a clear distinction between magnetism and static electricity. William Gilbert credited with establishing the term "electricity".
  • William Gilbert also designed the versorium: which is  device that detects the presence of statically charged objects. 
  • After In 1762 Swedish professor Johan Carl Wilcke invented a device later named electrophorus that produced a static electric charge. 
  • And after johan carlwilcke., By 1800 Alessandro Volta had developed the voltaic pile, a forerunner of the electric battery.

  • The discoveries of Michael Faraday formed the foundation of electric motor technology in the electrical world. 
  • Than after In the 19th century, research into the subject started to intensify. Notable developments in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, of Michael Faraday (the discoverer of electromagnetic induction in 1831), and of James Clerk Maxwell, who in 1873 published a unified theory of electricity and magnetism in his treatise Electricity and Magnetism.
  • Electrical Engineering became a profession in the later 19th century.
  •  Practitioners had created a global electric telegraph network and the first professional electrical engineering institutions were founded in the UK and USA to support the new discipline. 
  • Although it is impossible to precisely pinpoint a first Electrical Engineer, Francis Ronalds stands ahead of the field, who created the first working electric telegraph system in 1816 and documented his vision of how the world could be transformed by electricity.
  • Over 50 years later, he joined the new Society of Telegraph Engineers (soon to be renamed the Institution of Electrical Engineers) where he was regarded by other members as the first of their cohort..
  •  By the end of the 19th century, the world had been forever changed by the rapid communication made possible by the engineering development of land-lines, submarine cables, and, from about 1890, wireless telegraphy.

  • Practical applications and advances in such fields created an increasing need for standardised units of measure. 
  • They led to the international standardization of the units volt, ampere, coulomb, ohm, farad, and henry. This was achieved at an international conference in Chicago in 1893.
  •  The publication of these standards formed the basis of future advances in standardisation in various industries, and in many countries, the definitions were immediately recognized in relevant legislation.
  • During these years, the study of electricity was largely considered to be a subfield of physics since the early electrical technology was considered electromechanical in nature. The Technische Universit├Ąt Darmstadt founded the world's first department of electrical engineering in 1882. The first electrical engineering degree program was started at Massachusetts Institute of Technology (MIT) in the physics department under Professor Charles Cross
  • though it was Cornell University to produce the world's first electrical engineering graduates in 1885.
  •  The first course in Electrical Engineering was taught in 1883 in Cornell’s Sibley College of Mechanical Engineering and Mechanic Arts.
  • It was not until about 1885 that Cornell President Andrew Dickson White established the first Department of Electrical Engineering in the United States.
  •  In the same year, University College London founded the first chair of electrical engineering in Great Britain.
  •  Professor Mendell P. Weinbach at University of Missouri soon followed suit by establishing the electrical engineering department in 1886.
  • Afterwards, universities and institutes of technology gradually started to offer Electrical Engineering programs to their students all over the world.
