Electrical and Electronics Engineering is a field of engineering is not restricted to the world as electric, but generally study the applications of electricy, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. It now covers a range of subtopics including power, electronics, control systems, signal processing and telecommunications etc., Electrical engineering may include electronic engineering where the distinction and difference is made in the subject of review and depth of study. Electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmissions and electric motor controls. In fact electrical engineers are usually concerned with using electricity to transmiting of energy and depth of study is not restricted or binded.
