The difference between electrical and electronics engineering is often blurred, but it is generally true to say that electrical engineers are concerned mainly with the large-scale production and distribution of electrical power, while electronics engineers focus on much smaller electronic circuits.
In an electronics engineering degree, you are likely to develop an expert understanding of the circuits used in computers and other modern technologies, and for this reason electronics engineering is often taught alongside computer science. An electrical or electronics engineering degree will also overlap with mechanical and civil engineering.
