Electrical engineering is a branch of engineering that focuses on the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph and electrical power supply. This field covers a wide range of subfields including power engineering, telecommunications, radio-frequency engineering, signal processing, digital electronics, and microelectronics. Electrical engineers work on a diverse array of technologies from the design of household appliances, electric power stations, and wiring and lighting in buildings, to telecommunications systems, electrical power systems, and circuit design. Developments in electrical engineering have profound impacts on other fields like computing, mechanical and civil engineering, and are integral to innovations in renewable energy, transportation systems, and medical technologies.
