What is electrical engineering?

Electrical engineering is an important branch in engineering universities and colleges that involves studying, designing, and applying devices, equipment, and systems powered by electricity. It also examines the direct or indirect usage of electricity in electronic and electromagnetic devices. After auxiliary services like the electric telegraph and the telephone became ubiquitous, electrical engineers saw their career opportunities swell in the late 19th century.

From the 20th century, electricity has driven most of the technical progress. Electrical energy powers most modern inventions. Electrical engineering now spans a broad range of fields, including radio-frequency engineering, power engineering, computer engineering, electronics, systems engineering, signal processing, telecommunications, instrumentation, photovoltaic cells, photonics, and optics. Due to a crossover of these electrical engineering disciplines with other branches of engineering, many specializations have sprung up. These branches include electromagnetics and waves, hardware engineering, power electronics, electrochemistry, microwave engineering, renewable energies, mechatronics/control, nanotechnology, and electrical materials science.

Electrical engineers perform varied tasks due to the applicability of their knowledge in diverse fields. They work onboard naval and merchant ships, in the cleanrooms of a semiconductor fabrication plant, inside a mine, or on the site of solar and nuclear power stations. Electrical engineers also supervise other professionals ranging from computer programmers, electricians, scientists, and other engineers.
