Opportunities

Career Scope of Electrical Engineering

Electricity has become the basic need for survival of human beings globally. From household to industrial plants, communication and satellite navigation system, electronic equipment, computers etc., all require electricity. Electrical engineering is one of the core fields of engineering, always evergreen in terms of scope and job prospects. Electrical Engineering is the heart of whole engineering discipline. Nowadays, we see Electronics playing an important role in the implementation and control of Electrical Machines. Keeping this in mind the course has transformed from core electrical Engineering into a fusion of Electronics and Electrical and has been renamed as Electrical and Electronics engineering or simply EEE.
           Electrical engineering is the study and application of electrical systems for use in different environments. As an academic subject it involves the study about transmission and generation of electrical power, electrical circuit design, electronics, and instrumentation systems. In depth knowledge of electronic devices and circuits is also required. The application of computer-based systems in design, analysis and operation of power systems is also taught.
