Big subjects in electrical engineering include power generation, automation and control, semiconductors, and information technology (radio waves and computer). To meet new needs, electrical engineering produced new specialties, such as electronic engineering and software engineering.
History[change | change source]
When the industrial era began, we needed to study mathematics, physics and chemistry to help support it. In the late 19th century when electricity was used more, a new branch called electrical engineering was invented. When radio became important, many engineers worked at it, and their branch was later expanded to cover electronic engineering.
