What is electronics and electrical engineering?

electronics and electrical engineering

The lives of people in the 21st century revolve around electronic gadgets. At your home or workplace, you can always spot an electronic device supporting whatever activity you are doing. For instance, you schedule an appointment with a doctor using a phone, which is an electronic device. Similarly, smartwatches, gaming products, household products such as refrigerators, etc. are all electronic devices. So it is appropriate to refer to electronics as the backbone of modern human life. 

Since electronic gadgets have revolutionised our lives, we must understand the science of making these gadgets. 

What is electronics engineering in simple terms?

What is electronics engineering

In layman’s terms, electronic engineering is the study of electronic gadgets or systems. Electronic engineering is concerned with designing, ideation, manufacturing, operating, and controlling an electronic system. An electronic engineer also develops and designs software for such electronic devices. Electronic engineering focuses on the use of semiconductor materials to build an electronic device.

What is the difference between electrical and electronics engineering?

This branch of engineering is closely related to electrical engineering and is often misunderstood as the same. However, certain differences make electronic engineering a separate branch of electrical engineering. 

While electrical engineering is concerned with the conversion of power in an electrical system, electronic engineering is about maintaining the flow of electrons in an electronic device. Also, electronics engineering is concerned with semiconductor devices and the active components of these semiconductor devices. Electrical engineering, on the other hand, uses passive components such as resistors and inductors. 

The functioning of an electronic device

An electronic device can be your toaster, your grinder, or your dryer. Such devices are designed by an electronic engineer. These electronic devices have become an integral part of modern human life. An electronic circuit combined with electricity makes gadgets that make human life easy. 

The differences between electrical and electronic devices are easy to understand if you can understand how electronic devices function. For this purpose, it is imperative to know what an electronic engineer does. An electronic engineer designs, switches, and amplifies the electricity, or flow of electrons, in an electronic device. 

An electronic device has an electric current flowing through it. This electric current carries signals with it, which helps in the manipulation of data. Also, to let current flow in an electronic device, the circuit is built to control voltage through batteries or generators. An electronic circuit, on the other hand, is designed to process low-amplitude energy rather than convert it to different forms. Resistors help in controlling voltage and energy. 

Also, electronic circuits have diodes that ensure that the electric current flows in only one direction. Diodes convert AC into DC to ensure this one-way flow of current. Electronic devices can also process information and manipulate data. Another important function of electronic circuits is to amplify electric current. 

Every electronic device has transistors to do so. An electronic device’s structure can be simple or complex, depending upon its application and use. A complex electronic circuit implies the use of more components, such as optical-electronic components, etc.

DIY projects for electronics engineering students

Engineers are the assets of a country and the bearers of innovation. Every country depends on engineers for technological advancement and industrial growth. In this regard, it becomes imperative that due consideration be given to the education of engineering students. Education must be more than classroom lectures and written assignments. It should be a wholesome and worthwhile activity.

To break the cycle of monotony and rigorous lectures, project work can be a great helping hand. Project work offers a deeper insight into conceptual knowledge by letting students apply the theoretical knowledge to practice. For engineering students, it is important that they have hands-on experience with the latest technology. Project work for engineering students allows students to get that practical experience and be industry-ready. Through these project ideas, engineering students can get comprehensive knowledge and a firm grasp of the concepts of electronics. Engineering project ideas are designed to keep the trends of the industry in mind. This allows engineering students to be creative with projects and boost their confidence. 

Students can try a wide range of project work for engineering to develop their analytical and practical skills. These projects may range from easy to difficult depending on the level of difficulty.

Some of the electronics engineering final year project ideas are:

Scope of Electronics Engineering: Job Opportunities 

scope of electronics engineering

With the rise in technology and the dependence of man on gadgets, there has been evident growth in the field of electronic engineering. If you’ve ever wondered, “is electronics engineering a good career” then we’ve you covered. 

An electronic engineer must be good at designing, AutoCAD, project management, and programming languages for industries such as telecommunication, manufacturing, robotics, control engineering, computer engineering, aviation, and so on. 

A degree in electronics engineering often comes under electrical engineering. Electrical engineering has a wider scope and it includes electronic engineering within it. Therefore, a degree in electrical engineering would help candidates go for electronics engineering in particular. As for the eligibility criteria, there is more than one route to becoming an expert electronic engineer. Educational qualifications for becoming an electronic engineer can be understood as:

  1. 10+2 in the science stream (physics and maths as core subjects) 
  2. A bachelor’s degree in technology, applied technology, or engineering (B.tech/B.E) 
  3. A postgraduate degree in technology, applied technology, or engineering (M.tech/M.E)


Diploma in electronic engineering after 10th or 10+2 

In addition to these educational qualifications, a candidate has to gain some practical skills as well to ensure a good job offer. A bachelor’s or an equivalent degree opens the door to many entry-level and executive-level jobs in electronics engineering. A master’s degree, however, can be acquired to fetch even more decent jobs. Upon getting an education and acquiring skills, a candidate can try to fetch a job in various industries as he/she may find it interesting. There are several demanding job roles in electronics engineering which are mostly sought by a talented pool of freshers. These job roles are:

  1. Aerospace engineer
  2. Biomedical engineer
  3. Electricians
  4. Engineer in electronics or communication
  5. Lecturer/Professor
  6. Software/Hardware engineer 
  7. System engineer
  8. Technicians

This list of job roles is inclusive in nature. As the field of electronic engineering is constantly evolving, there are many growth opportunities coming for talented engineers.
