Electrical Engineering?

Inception, expansion and change of universe is effect of conversion of energy between different forms. We are surrounded with energy waves and processes. Types of energy can be classified in many forms viz. electrical energy flowing in electrical appliances and overhead lines, mechanical energy in all moving objects and machines, potential energy in falling water, heat energy in sun rays, sound energy during speech, wind energy in flowing wind, tidal energy in sea and many more. In all type of energy forms, electrical energy is most feasible and easily convertible in other forms of energy.

Now a days we generally hear through television, newspaper, magazines and other media sources, words like electric vehicles, renewable energy, intelligent control, robust control, smart grid, solar energy, electrical locomotives, electric trains etc. What are these all about? How these things originated? Why we need these? How these things are going to change our life? All of these questions generally hit our mind.

To find out the answers of these questions and to know about electrical energy and its key features like conversion in other forms, transferable form one place to other, feasibility etc. we need to study electrical engineering.

Electrical Engineering

Electrical Engineering is a field of engineering that deals with the study of electricity, electronics and magnetism. Electrical engineering is an amalgamation of electrical, electronics and communication, instrumentation, computer engineering etc. and is the largest of all engineering disciplines.

Electrical engineering includes the fields like generation, transmission and distribution of electrical energy, electrical circuit designing, electronics, instrumentation, control system, electrical and electronic networks etc. Electrical engineers work in designing and research in electrical systems, supervise and plan manufacturing process of high end electrical systems, problem identification and the selection of appropriate technical solutions, test equipment and procedures to the manufacture and production of safe, economical, high-performance products and services. Electrical engineers work to combine technology with creativity, taking ideas and turning them into reality.


The scope in electrical engineering lies in different areas in public sector as well as private sector. Some of the areas are:


Electrical Engineer in India

A bachelor’s degree in electrical engineering is the minimum requirement to become a qualified electrical engineer. A post graduate degree is required for research or teaching posts and an additional degree in business administration is desirable for managerial services.

Selection in the graduate courses is based on marks secured in 12th standard science stream. If we talk about best colleges for engineering in India then anyone can easily name IITs and NITs. Other state and private universities are also offering undergraduate and post graduate courses. If you ask for best university in Rajasthan, only one name JK Lakshmipat University come in my mind. The Institute of Engineering & Technology, JK Lakshmipat University stands in top colleges for engineering in Rajasthan. Selection to the postgraduate courses is through graduate aptitude test in engineering (GATE). B.E/B.Tech courses are of 4 years duration and post graduate course M.E/M.Tech are of 2 years duration.

Major Players:

There are thousands of companies working in the fields of electrical engineering which require electrical graduates. Name of some major companies are given here:

Public sector:


Private sector:

ABB Siemens Rockwell Orient Crompton & Greaves
Venus M-Tek Reliance Jindal Areva
Bajaj Eveready Khaitan Lloyd Tata
Maxx Philips Panasonic Orpat GE
Birla Kirloskar Torrent Techno DLF
JK Texas L&T Powertek Suzlon
Azure Moser Baer Auro Indowind Schneider
GM Adani Essar Usha NEPC

These are some major industries in my knowledge. One can find more by simply google on net. The selection criterion in most of the private companies and some of the state ventures is graduate degree while most of the centre government jobs in India require additional GATE score.
