Why Electrical engineering?
·      Electrical engineering is one of the largest, broadest and evergreen branches of core engineering since long time.

·      In Modern era one cannot imagine life without electricity.

·      Electricity has changed the lifestyle of the people and day by day the need of electricity is increasing.

·      Electrical engineers are developing clean and efficient renewable energy and electric/ hybrid vehicles to radically reduce our dependence on fossil fuel and to reduce our CO2 emission.

·      As in the development of the one electron transistor in nanotechnology to the very large Power Engineering generator and transmission lines Electrical Engineering has a key role.

·      Electrical engineering is the parent branch of all electronics and communication, computer science and information technology branches.

·      Electrical engineering gives you exciting, rewarding, challenging, flexible and career building platform.

Who should select Electrical engineering as a career?
Those who have desires of learning:

·      Mathematics and designing skill.

·      Complex problem solving.

·      Sciences and its correlations with electrical laws and theories.

·      Mechanism of operation of electrical tools and components.

·      Development and design of power system, electrical machines and electrical appliances.

·      To work with cutting edge technology and software.

·      Ways to improve the efficiency and effectiveness of power system, electrical machines and electrical appliances.

·      How to work on shop floor with safety and precautions.

·      How to work with time management and flexibility in terms of time and location.

·      Inquisitive skills.

·      Creativity and thinking skills.

·      Teamwork attitude and mind set for hard work.

·      How to work in shift time.

Does Electrical engineering have any scope after four years?
·      Yes, it has a scope of employment, entrepreneurship and further study.

·      Government is focusing on Entrepreneurship and more number of projects and companies in power sector and Infrastructures are coming up.

·      Electrical engineering is a Core and essential branch. Hence, very few external factors can affect its growth.

·      Irrespective of core electrical engineer companies, all the industries (it maybe SMES, SSI, LSI or MSI) like requires Electrical engineers.

·      Students have huge scope in public sector units. If they clear GATE examination, they may get direct interview call and placement in public sector units like NTPC, Power Grid, BEML, BHEL and ONGC.

·      Strong job opportunities are available in almost all fields like design and development, production, Maintenance, Services, Project Planning, execution and testing.

·      Many core electrical companies and other companies like ABB, alstom, Siemens, Cummins, NTPC PowerGrid, LNT Tata Power comma Reliance Reliance Power BHEL ISRO ONGC, Ambuja Cement, Suzlon Essar group, ABG group, Godrej, Tata Group, GE energy, Mahindra, HAL, Thermax, etc

·      It has a scope of employment and further studies in foreign countries also.

·      Girls can also work in project, consultancy and design team.


In addition to the above strengths and scope for electrical engineering, few concerns are also there which one should consider while selecting electrical engineering as a career option.

·      Lack of laboratory and research facilities for electrical engineering in many institutes will affect on knowledge and compatibility of students.

·      For the better growth students should be there did to work at remote places and relocation process.

·      Ready to travel across country, even in hard condition and at remote places.

Difference between Electrical engineering & Electronics and communication engineering
·      Electrical engineering is the field of Engineering that generally deals with the study and application of electricity while electronics and communication is an engineering discipline which deals with nonlinear and active electronics components and modes of communication like analogue and digital.

·      About 60% of subjects to be studied in Electrical and EC engineering are common.

·      Electrical engineering is more concentrating on electrical machines and power system while EC Engineering has more concentration on integrated circuits and communication.

·      As per the current scenario job opportunities for electrical engineer is more in government as well as in private sector as compared to EC engineer.
