Electrical engineering From Wikipedia, the free encyclopedia Electrical engineering,often referred to as the electrical and electronic engineering (EEE), is a field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism.
It is a very broad area that encompasses the design and study of various electrical & electronic systems, such as electrical circuits, electrical generators, electric motors, transformers, magnetic devices & materials, electromagnetic and electro mechanical devices, electronic devices, electronic circuits, electronic materials, optical fiber’s, optoelectronic devices, computer systems, radio, television, telephony, telecommunications, wireless, microwave systems, mobile telephony, radar, data communication, computer networking, nanotechnology, photonics, micro electromechanical systems, etc.
Electrical engineering may or may not include electronic engineering. Where a distinction is made, usually outside of the United States, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems including computers and integrated circuits.
Alternatively, electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to transmit information. More recently, the distinction has become blurred by the growth of power electronics.
The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. The modern Electrical Engineering subject may cover a range of subtopics including power, microelectronics, VLSI, nanotechnology, control systems, mechatronics, robotics, nonlinear systems, computer engineering, systems analysis, signal processing, telecommunications, data communications, communication systems, information theory.
