Difference between Electrical Engineering and Electronics Engineering

Electrical engineering

Electrical engineering is the field of engineering that is generally concerned with the study and application of electricity, electronics and electromagnetism.

Electronic Engineering

Electronic engineering is an engineering discipline where non-linear and active electrical and electronics components and electron tubes, and semiconductor devices, especially transistors, diodes and integrated circuits, etc., are used to design electronic circuits, devices and systems.

The main differences between electrical and electronic engineering below are the main differences between electrical and electronic engineering that prevent such confusion between electrical and electronics engineering as they are thin terms related to each other but they are not the same.

Electrical Engineering = Study and Utilization / Application of Flow of Electrons.

Electronics Engineering = Study and utilization / Application of Flow of Charge (Electron & Holes).

1. As we know we only study the flow of electrons in a conductor and an insulator, but in the case of semiconductors, we study the flow of both electrons (negative charge) and holes (positive charge).

2. In addition, electrical components and equipment use alternating current (AC) / voltage and are larger in size and require 230V (in the UK) and 110V (in the US) single phase AC voltages where in industry and power stations It can be 11kV and for transmission, it can be over 400kV.

3. Whereas, electronic components require very low direct current (DC) / voltage such as 3–12V and can be very small in size. For example, a micro processor chip may contain hundreds / thousands of small electronic components.

4. Another major difference between electrical and electronic engineering is that an electric circuit / network can only power an electric machine where the electronic circuit plays a role as a decision-making component and device as they follow the input instruction And a specific and functioning circuit defined by design.

5. Also note that "electronics engineering is one of the field / branch of electrical engineering" In other words, electronics engineering is an elder son of electrical engineering
