Electrical and Electronics Engineering is a discipline of engineering concerned with the design, maintenance and development of electrical control systems and equipment. It is the study of the applications of electricity, generally those involving current flow through motors, generators and other conductors. Students in this field will learn about the conduction of electricity through gases or a vacuum as well as through semiconducting materials. The discipline includes topics like image and signal processing, electromagnetics, electronic components and materials, microwave technology, and microelectronics.
