Electrical engineers design of complex energy systems ...
... And electronic circuits.

Electrical engineering is a field of engineering thaudy and application of electricity,t generally deals with the st electronics and electromagnetism. This field first became an identifiable occupation in the second half of the 19th century after commercialization of the electric telegraph, telephone, and electricity distribution and use. Subsequently, the broadcast media and electronic recording made part of everyday life. The invention of the transistor and subsequently brought down the integrated circuit electronics cost to the point that can be used in almost any household object.

Electrical engineering has been subdivided into a wide range of subfields including electronic, digital computers, power engineering, telecommunications, control systems, RF engineering, signal processing, instrumentation and microelectronics. The issue of electronic engineering is often regarded as its subfield but intersects with all other subfields, including power electronics electrical engineering.
