Scope of Electrical and Electronics Engineering
Imagine your life without electricity and consumer durables like television, refrigerator, microwave, etc. – seems mundane and hard to survive. Isn’t it? Electricity and electronic appliances have become one of our basic needs in day-to-day life. With our increasing dependency on electrical and electronic products, the scope of electrical and electronics engineering has also grown in giant strides as compared to previous decades. If we talk about job quotient in the different sectors of electrical and electronics engineering, it is ever-increasing to meet the variegated needs of the consumers in India as well as abroad. Be it transport, banking, other private and public sectors and even educational premises, electrical and electronics engineering has a vital role to play in any environment.
Let’s read further what electrical and electronics engineering (EEE) is all about.
An Introduction to Electrical and Electronics Engineering
Before delving deeper into the scope of electrical and electronics engineering, it’s important to know about what electrical and electronics engineering is meant for.
What is Electrical Engineering (EE)?
Electrical engineering is the core study of the applications of electricity and electronics, which is one of the most chosen streams by engineering students. It was introduced dates back to the 19th century. ‘Faraday’s Law of Induction’ brought revolution in Electrical Engineering by introducing new concepts of current flow. Mainly the electrical engineering study involves:
- Generation of electricity
- Transmission of electricity
- Distribution of electricity
The pioneer discoveries in electrical engineering are induction motors by Nicola Tesla, electric light bulb by Thomas Alva Edison, and radio by Guglielmo Marconi. These innovators transformed the scenario by implementing the concept of electrical engineering into practical devices. The specialized categories of EE encompass power generation and transmission systems, motors, batteries and control systems.
What is Electronics Engineering?
The electronics engineering revolves around the study of electronic devices, circuits, equipment, and systems. While pursuing electronics engineering, students learn to utilize a wide range of electronic components from analogue to digital components, microcontrollers, microprocessors, and programmable logic devices. The specific branches of electronic engineering mainly include:
- Analogue Electronics
- Digital Electronics
- Power Electronics
- Embedded Systems
- Communication Systems
In 1904, John Ambrose Fleming invented the thermionic diode vacuum tube and this invention is referred to as the ‘birth of electronics’. This vacuum tube worked as the foundation of all electronics of that time, including television, and radar. Later on, transistors replaced the vacuum tubes in 1947, which was the invention of William Shockley, John Bardeen and Walter Brattain at AT&T’s Bell Laboratories.
Difference between Electrical Engineering and Electronics Engineering
Electrical and electronics are two related forms of engineering. However, most of the engineering UG and PG courses club these technologies together since both the technologies complement each other. B.Tech in Electrical and Electronics Engineering, B.E in Electrical and Electronics Engineering, and M.Tech in Electrical and Electronics Engineering are the major courses offered at engineering institutions. Electrical and electronics engineering can be distinguished by the functions performed in both the specializations. Below table might be a help:

Why Electrical and Electronics Engineering come together?
The mechanism of almost all modern appliances is designed with the combination of electrical and electronic circuitry. Hence, studying both the forms of engineering altogether has become mandatory for aspiring students to learn the circuit programming of the appliances wholly. The electric circuits in an appliance help it operate while the electronic circuits interpret the signals or instruction transmitted by the users and let the machine perform accordingly.
Expanding Scope of Electrical and Electronics Engineering with Government of India Initiatives
Scope of Electrical Engineering
‘Vision 2022 for Indian Electrical Equipment Industry’- an initiative by the Ministry of Heavy Industries and Public Enterprises has amplified the scope of electrical and electronics engineering in India.
Estimated growth (in US$ Billion) of the electrical engineering market by 2021-22 is as follows:
With the help of the above illustration, it can be said that the EE market in India is expected to see unprecedented growth as the projection for ‘Net EE Market’ is USD 100 Billion. It is anticipated that the growth of generation equipment segment might reach up to Rs. 125,000 crore whereas T&D equipment segment will touch the figure of Rs. 375,000 crore. On the other hand, the partnership of Indian electrical engineering in global EE trade will be 2% by 2022, which is currently hanging around 0.8%. The import rate is also expected to decrease by 7-8% due to continual advancements in Indian electrical engineering.
The aforesaid stats show that Indian EE Ecosystem is on the right path and the scope is all set to increases every day. As far as job opportunities are concerned, the report of Vision 2022 says that there will be direct recruitment of 1.5 million and indirect recruitment of 2 million electrical engineers. This initiative or vision is all about the ambitions and capabilities of the Indian electrical equipment industry.
Scope of Electronics Engineering
Under the‘Electronics System Development and Maintenance (ESDM)’ scheme, the government puts endeavors to impart training for up-skilling the existing manpower for service and manufacturing industry. ESDM is also referred to as a prerogative of Prime Minister of India under ‘Make in India… Made in India’ scheme. Read the below pointers to know how the government’s indulgence in ESDM has been enlarging the scope in electronics engineering.
- Government has introduced Phased Manufacturing Programme (PMP) and fiscal interventions to promote the production of electronic products within the national boundaries.
- Information Technology Agreement (ITA-1) of WTO has been focusing on devising the right methods for encouraging the production of electronic goods.
- Fuelling electronic industry by launching incentive mechanisms such as interest subsidy, credit default guarantee, etc. to support the expansion of existing units and setup of new manufacturing units.
- Exemption on the import duty levied over capital equipment to reduce the expenditure on capital of existing as well as new manufacturing units.
- Government support for ATMP (Assembly, Testing, Marking and Packaging) lines for identified electronic components/ products.
- Launch of new schemes aimed at infrastructural development along with the amendments in the prevailing Electronics Manufacturing Clusters (EMC) scheme by boosting Brownfield and Greenfield manufacturing clusters.
Along with the above-information, the below table will describe how the reduced import from 2015 to 2017 is going to impact the electronic industry:

It is predicted that the scope of electrical and electronics engineers will multiply largely in the core industries. The companies are expected to rely upon the expertise of skilled engineers only to handle the tasks like manufacturing of electrical and electronics devices and components. It depicts that the engineers are going to be in demand for a very long time.
The projections for the job opportunities by 2026 say that the job size of 324,600 in 2016 will touch 345,800 jobs for electrical and electronics engineers with a 7% hike. Hence, the total increase in job opportunities would be 21,200. If talk m about the electrical engineers only, the number of jobs in 2016 were 188,300 and it will witness a hike of 9% (i.e. 16,200 in numbers) by 2026. On the other hand, there were total jobs for electronics engineers (except computers) 136,300 in 2016. It will see a growth of 4% and 5,100 new opportunities will be added to respective industries.
This entire write-up is based on facts and figures, which proves the dominance of electrical and electronics engineering- not just currently, but in future as well the scope of electrical and electronics engineers will remain unaffected by the factors like technical advancements and advancements, recession, etc. Hence, the moral of the story is that the students looking to pursue engineering education after 12thstandard can go for electrical and electronics engineering, without a doubt, as it is one of the burgeoning streams of engineering in the coming future.
