Electrical engineering is an engineering branch that focuses on the generation, transmission, as well as distribution of electrical power. On the other hand, electronics engineering centers on design and development of electronic devices, circuits, and systems.

Electrical and electronics are often mistakenly used in place of each other. However, the two terms have different meanings. Let us understand the difference between electrical and electronics in detail in this article.

## Difference between Electrical and Electronics Engineering

Let us now understand the difference between the two in a little more detail:

## What is Electrical Engineering?

This field of engineering deals with the study of electricity, its equipment, devices and systems. On a broader level, it deals with the study of how electrical power is used for producing electrical energy and how its function can be regulated. This branch of engineering deals with the manipulation of electrical and electromagnetic phenomena to create useful products.
