Electrical engineering is a field of engineering that generally manage with the study and application of electricity, electronics, and electro magnetism. This retrive first became an identifiable profession in the later half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power trading and use. Subsequently, broad casting and recording media made electronics part of daily life. The creation 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 sub fields including electronics, digital computers, power engineering, tele communications, control systems, radio-frequency engineering, signal processing, instrumentation, and microelectronics. Many of these sub disciplines overlap and also overlap with other engineering branches, connect a large number of line such as hardware engineering, power electronics, electro magnetics & waves, microwave engineering, nanotechnology, electro chemistry, renewable energies, mechatronics, electrical materials science, and many more.
Electrical engineers typically hold a degree in electrical engineering or electronic engineering. prepare 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 (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 necessary of a project manager. The tools and tool that an individual engineer may need are similarly variable, ranging from a simple voltmeter to a top end res to useful design and production software.
