15 Facts About Electrical engineering

Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism.

Electrical engineering is divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics.

Electrical engineering designed the versorium: a device that detects the presence of statically charged objects.

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.

The first course in electrical engineering was taught in 1883 in Cornell's Sibley College of Mechanical Engineering and Mechanic Arts.

Electrical engineering introduced the use of semiconductor junctions to detect radio waves, when he patented the radio crystal detector in 1901.

Today electrical engineering has many subdisciplines, the most common of which are listed below.

Telecommunications Electrical engineering focuses on the transmission of information across a communication channel such as a coax cable, optical fiber or free space.

Control Electrical engineering focuses on the modeling of a diverse range of dynamic systems and the design of controllers that will cause these systems to behave in the desired manner.

Control Electrical engineering has a wide range of applications from the flight and propulsion systems of commercial airliners to the cruise control present in many modern automobiles.

Electronic Electrical engineering involves the design and testing of electronic circuits that use the properties of components such as resistors, capacitors, inductors, diodes, and transistors to achieve a particular functionality.

At many schools, electronic engineering is included as part of an electrical award, sometimes explicitly, such as a Bachelor of Engineering, but in others, electrical and electronic engineering are both considered to be sufficiently broad and complex that separate degrees are offered.

In most countries, a bachelor's degree in Electrical engineering represents the first step towards professional certification and the degree program itself is certified by a professional body.

Today most engineering work involves the use of computers and it is commonplace to use computer-aided design programs when designing electrical systems.

Electrical engineering has an intimate relationship with the physical sciences.
