What is Electrical and Electronic Engineering?

The branch of electrical engineering deals with practical applications of electricity in all its forms, including those of the field of electronics, whereas the branch of Electronics engineering is concerned with the usage of the electromagnetic spectrum. People assume electrical engineering and electronic engineering as the same but several differences exist between the two disciplines.

Electronics engineering is a part of electrical engineering as it deals with electronic circuits and devices and also it covers very-large-scale integration known VLSI.

Electronics engineers are expected to design and test the electronic circuits behind a wide range of applications in industrial, communications, transportation, and more. For their work, they utilize mostly passive electronic components (such as resistors, inductors, capacitors, and diodes).

Similar to electronics engineering, electrical engineering is also a broad field as it involves working on electronic systems, power systems, electromagnetism, and much more. Virtually every type of organization requires some form of electrical system or machinery to carry out their process of business

Electronics Engineering and its area of specialization

What is Electrical and Electronic Engineering

Electronics engineering is divided into several subfields, which include fields such as telecommunications, robotics, and computer engineering:

  • Telecommunications engineering: this branch of engineering deals with the systems and devices that enable data and voice communications.
  • Robotics engineering: this field deals with the design and manufacture of robots and also robotic systems for industrial automation, healthcare, agriculture, transportation, and a lot more. Robotics engineers spend most of their lives in designing, configuring, and testing robots, alongside designing the software systems that control them and the outside environment.
  • Computer engineering: this field of study includes computer science with electronics engineering to develop hardware components and software programs for computers.

Computer engineering is a huge subfield as it encompasses software and firmware development, and much more. Computer engineers ought to design, test, integrate, and innovate computer and computer-based software and hardware systems and work in all kinds of industries that utilize electronic circuits and computerized systems, e.g., defence, nanotechnology, healthcare, radio, and satellite communications, etc.

Things to Know About Electrical Engineering before you enter into this field of vast opportunities:

Power systems engineering: this is a core field of electrical engineering that deals primarily with the generation, utilization, transmission, and distribution of electric power, as well as the equipment and machines involved.

Instrumentation and control engineers may utilize electronic components and devices that test for pressure, temperature, speed, volumetric flow through pipes, and more.

Systems engineers utilize systematic thinking and problem-solving methodologies, such as system architecture, system modelling and simulation, reliability analysis, and, of course, decision making.


Electrical engineering and electronics engineering are branches of the same tree for sure but, in many cases, engineering students at the university take up the same courses for the first few years before they decide to specialize in one or more aspects. Are you among those students whose aim is to become an electrical or electronic engineer? are you passionate about pursuing your career in this field? probably that is the reason you have been reading this article all this while.
