Electronics Engineering and Electrical Engineering - Know the Difference

by Pankaj Sharma Digital Marketing Professional

Both electrical and electronics engineering might confuse you due to their names. However, both engineering fields are different in terms of knowledge, scope and job opportunities associated with them. Both the engineering disciplines involve electricity moving around a circuit that provides power to the products and machines. The similarity of engineering fields ends here.

Eligibility criteria, admission process, as well as the course structure remains the same. Thus, you only need to choose the engineering discipline for B.Tech admission based on your interest, and scope. This written piece will walk you through the difference of both the disciplines and provide you the benefits of electrical engineering and electronics engineering when both come together.

Working Areas of Electrical Engineer and Electronics Engineer

The primary difference between electrical and electronic circuits is that electronics circuits have decision making (processing) capability, whereas electric circuits do not have the same. An electrical circuit is simply responsible to provide power to machines with electricity. Whereas, an electronic circuit can interpret a signal and perform tasks that suit the circumstance. For example, an induction stove beeps when it has finished cooking.

Modern appliances perform all the functions with an amalgam of electronic and electrical circuits. For example, a washing machine comprises an electric circuit with a socket, fuse, motor, which aids the rotation of the drum.

An individual has to input the desired wash cycle and temperature using the control panel on the washing machine. The electronic circuits interpret these instructions that users input. An electronic circuit interprets the commands and transmits signals to the electric circuit to operate the motor based on the information.

The Scale Difference

Electronic components are tiny and might require a direct current voltage. For example, a microprocessor that can fit at the tip of your finger might contain hundreds of tiny components. On the other hand, electrical components are larger and use alternating current voltage. Most of the electronic components use 3-12 volts of DC, whereas electrical appliances require around 230 volts AC.

Products such as computers have more electronic components than electrical components. Whereas, large industrial sites such as power stations have more electrical components.

How do they work together?

With the technological advancements, people have realised the importance of electrical and electronics engineers working together. The electronic and electrical circuits can link together via transistors or relays. Typically, these are switches that are operated by a small current passed via an electronic circuit. Therefore, engineers use these tiny electronic components to operate much larger electrical equipment. Via the amalgam of electrical and electronic circuits, safety of household and industrial products is a common thing. Additionally, it helps in the efficient use of energy.


Now you know the difference between electrical and electronic engineering. Both have equal importance in the functioning of different circuits. Considering both electrical and electronics benefits, institutes tend to offer EEE in BTech, i.e. a B.Tech degree majoring in electrical and electronics engineering. This degree can help in applications of both electrical as well as electronics engineering.
