This article treats electronics engineering as a subfield of electrical engineering, though this is not typical use in some areas. See electrical engineering (terminology) for details. Electrical engineering (sometimes referred to as electrical and electronics engineering) is a professional engineering discipline that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century with the commercialization of the electric telegraph and electrical power supply. The field now covers a range of sub-disciplines including those that deal with power, control systems, electronics and telecommunications.

The term electrical engineering may or may not encompass electronics engineering. Where a distinction is made, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronics engineering deals with the study of small-scale electronic systems including computers and integrated circuits. Another way of looking at the distinction is that electrical engineers are usually concerned with using electricity to transmit energy, while electronics engineers are concerned with using electricity to transmit information.
