Electrical engineering is a branch of engineering focused on the study and application of electricity, electronics, and electromagnetism. Emerging as a profession in the late 19th century with the commercial use of the electric telegraph and electrical power systems, it now encompasses numerous subfields such as power engineering, electronics, control systems, signal processing, and telecommunications. For a detailed overview, refer to the outline on electrical engineering.
Classification
Electrical engineering can be described as all of the following:
- Academic discipline – branch of knowledge that is taught and researched at the college or university level. Disciplines are defined (in part), and recognized by the academic journals in which research is published, and the learned societies and academic departments or faculties to which their practitioners belong.
- Branch of engineering – discipline, skill, and profession of acquiring and applying scientific, economic, social, and practical knowledge, in order to design and build structures, machines, devices, systems, materials and processes.
