What is difference between electronics & electrical engineering?

The number of differences between electrical and electronics engineering may vary, depending on the context in which the question is asked. Some distinctions which may exist in academe may not exist in the business world. There is also a significant amount of overlap, not only between electronics and electrical engineering, but with other engineering disciplines as well. Most notable are the overlaps between electronics and computer engineering and with electrical and mechanical engineering. 

Electrical engineers generally deal with large-power applications, such as utility and industrial power systems, whereas electronics engineers deal with low-power systems such as computers and communications. Most work in electrical engineering makes use of knowledge of both electronics and electrical engineering. Power systems today are making increasing use of power electronics and digital controls for controlling power flow, and many electronic systems make use of milliwatt electro-mechanical components. 

Most electrical/electronic engineering programs today focus on electronics engineering. A few programs offer courses in basic machine theory and transmission lines that provide the fundamentals of electrical engineering, while some of the larger universities offer programs in power systems engineering. With the rapid growth in information technology, digital control systems, and robotics, EEs must have a solid understanding of electricity and magnetism as well as the ability to continually update their knowledge of electrical/electronics, mechanical, and chemical systems.
