Have you ever confused between electrical and electronics engineering?

What exactly is the difference between Electrical and Electronics engineering?

After my schooling, when it was time to take the engineering admission, I asked the same question to myself.

Now, I have completed my master’s graduation in electrical engineering. I think I’m very much eligible to answer your query.

I will explain electrical and electronic circuits, devices, and their functionalities.

Let’s see the detail description, differences, and similarities in electrical and electronics.

Difference between Electrical and Electronics

Let’s study electrical and electronics by comparing with one with another.

#  Content Electrical  Electronics
01 Definition Electrical technology deals with the generation, distribution, storage, and conversion of electrical energy/power, etc. Electronic technology deals with designing, amplifying,  and switching electrical energy with the help of different electronics equipment.
02 Fundamental Role In the electrical circuit, electrical energy consists of the flow of electron. In the electronic circuit, the energy consists of the flow of electron and hole.
03 Device Principle (Voltage & Current) The electrical devices produce the voltage and current. Electronic devices control the voltage and current.
04 Current Function(AC & DC) It works on Alternating Current (AC). The AC power may be a single-phase or three phases (220V/440V) in the ‘V’ to ‘kV’ range. Only the Direct Current (DC) work on it. The range of the voltage is ‘mV’ to ‘V’. The general rating of the voltage is 5V,12V,24V, etc.
05 Conducting Material In the electrical environment, the conductor is used.
Copper (Cu) and Aluminum(Al) are the best conductors.		 Only the semiconductor is used in the electronic circuit.
Example: Silicon (Si), Germanium (Ge), etc.
06 Specification of Component It consists of passive components.
Example: Resistor, capacitor, and inductor.		 It consists of active components.
Diode, transistor, oscillator are the best example of active components.
07 Function They cannot manipulate data. It manipulates the data to assign.
08 Electrical Power In the electrical circuit, the role is to monitor or control the high electrical power. An electronic circuit monitors or controls low power.
09 Decision-Making Device This electrical device cannot make a decision.
Example: The electrical bulb cannot make a decision.		 This device easily can make a decision.
The best example of an electronic device is Mobile. It can get a quick decision.
10 Energy Conversation Electrical energy converts into other forms of energy i.e heat, motion, or light. It does not convert into other forms.
11 Size Electrical devices occupy a large size and required more space. Electronic devices occurred in small sizes. You can easily transport the electronic circuit/pieces of equipment.
12 Example Transformer, Alternator Motor and Generator, Fuse, Circuit breaker and etc. are the example of electrical devices. Diode, Transistor, Thyristor, Microcontroller, etc. are the example of electronic devices.

13. Electrical and Electronic System

Electrical System:

In the electrical system network, electrical power is transmitting from generation to distribution system with their different types of equipment.

You can see the following network of an electrical system.

I hope the difference between electrical and electronic is clear with those 13 points. I have explained the different kinds of functions, aspects, working role, device energy/power role, etc in detail.

What is the Difference Between Electrical and Electronics devices?

The most dominant difference between both is, electrical devices convert electrical energy into another form of energy like heat, light, sound, etc.

An electronic device performs control/switching operation of electrical energy for the particular task.

Similarity between Electrical and Electronics Circuits

  1. Technically, the electrical and electronic devices both require a flow of electrons for the circuit operation.
  2. In both, electrical and electronic circuits, the transformer is used for transmitting the voltage.

  4. Why this education system is different and complex? Your explanation cleared my view after 8 yrs of my degree completion in EEE. I hate these teachers who failed to educate me and my fellow colleagues. I’m from Tamil Nadu. Here engineering has become marketing. No one cares about students life. Thank you for sharing this simple and clear explanation.

    • Hi Arun,

      Discussing the eduction system in India is a never-ending topic. I’m glad hearing your thoughts and opinion about our education system.

      I’m also happy as you find this tutorial simple and clear. Hope you enjoy reading other tutorials as well. I will try my best to keep the same harmony- simple and clear.

  12. Hi Dipali,

    It’s really useful for me. I too have this doubt. Your explanation was awesome Dipali. It would be grateful if you could give more basics tutorial.

  15. Hi Dipali, Nice explanation.

    I have a concern about the voltage rating of the electronic elements. For the HVDC application, the power rating would be in KW/MW.

  16. I want to gratitude you so that I have got a very clear illustration about the difference between electrical electronic engineering(also devices). Also I have got a core idea about what I want to know. I hope that I will find solution for many engineering problems by accessing your channel(or web site). THANK YOU VERY MUCH.
