12 Main Difference between Electrical and Electronics Engineering

12 Main Difference between Electrical and Electronics Engineering

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 a time to take the engineering admission, I asked the same question to myself.

Now, I have completed my master 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 the electrical and electronics by comparing with one with another.

Sr. No.  Electrical  Electronics
1 Definition The 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.
2 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.
2 Device Principle The electrical devices produce the voltage and current. Electronic devices control the voltage and current.
3 Useful Electrical Power It works on Alternating Current (AC).

The Ac power may be a single phase or three phases i.e 220V/440V or 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.

 

4 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.

5 Specification of Component It consists of passive components.

Example: Resistor, capacitor, inductor.

It consists of active components.

Diode, transistor, oscillator are the best example of active components.

6 Function They cannot manipulate data. It manipulates the data to assign.
7 Power Role In the electrical circuit, the role is to monitor or control the high electrical power. An electronic circuit monitors or controls low power.
8 Decision-Making Device This electrical device cannot make a decision.

Example: The electrical bulb cannot take a decision.

This device easily can make a decision.

The best example of an electronic device is Mobile. It can get a quick decision.

9 Energy Conversation Electrical energy converts into others form of energy i.e heat, motion or light. It does not convert into other forms.

System

Here, electrical energy is transmitting from generation to distribution system with their different types of equipment.

Electrical System

In this below picture, we are looking at the different kinds of electronic equipment.

Electronic Circuit

11 Size Electrical devices occupy large size and required more space. Electronic device occurred in small size. You can easily transport the electronic circuit/pieces of equipment.
12 Example Motor, Generator, Transformer, Alternator, etc. are the example of electrical devices. Diode, Transistor, Thyristor, Microcontroller, etc. are the example of electronic devices.

Hope the difference between electrical and electronic is clear with those 12 points. I have explained the different kinds of function, aspect, working role, device energy/power role, etc in details.

What is the Difference Between Electrical and Electronics devices?

The most dominant difference between both is,  electrical devices convert the 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

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