Electrical engineering is one of the newer branches of engineering, and dates back to the late 19th century. It is the branch of engineering that deals with the technology of electricity. It generally deals with the study and application of electricity, electronics, and electromagnetism. This 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. Subsequently, broadcasting and recording media made electronics part of daily life. The invention of 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.
    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, and microelectronics. Many of these 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 many more.


    Electrical and electronics engineers work primarily in research and development industries, engineering services firms, manufacturing and the federal government. They generally work indoors, in offices, but they may have to visit sites to observe a problem or a piece of complex equipment.
    Manufacturing industries that employ electrical engineers include automotive, marine, railroad, aerospace, defense, consumer electronics, commercial construction, lighting, computers and components, telecommunications and traffic control. Government institutions that employ electrical engineers include transportation departments, national laboratories and the military.
    Electrical engineers are instrumental in revolutionizing the lives of modern man. They are required by the industries manufacturing all the household and office appliances like refrigerators, televisions, computer, microwaves and what not. In our age of satellite-transmitted television and transcontinental computer networks, these engineers are high in demand. Electrical engineers also find employment in atomic power plants, hydroelectric power plants as well as thermal power plants.
