Which branch of engineering primarily deals with electrical systems?

The branch of engineering that primarily deals with electrical systems is Electrical Engineering. This discipline focuses on the study and application of electricity, electronics, and electromagnetism. Electrical engineers design, develop, and maintain electrical equipment and systems, which can include anything from small electronic devices to large power networks. They work on a wide variety of technologies, such as electrical circuits, power generation and distribution systems, communication systems, and control systems.

Civil Engineering primarily involves infrastructure projects, such as buildings, roads, bridges, and water supply systems. Mechanical Engineering deals with mechanics, dynamics, and the thermal processes of machines and mechanical systems. Aerospace Engineering focuses on the development of aircraft and spacecraft, involving fluid dynamics, structural analysis, and propulsion systems. Therefore, Electrical Engineering is the only field among the choices that specializes in electrical systems specifically.
