Civil engineering is a professional engineering discipline that deals with the design, construction and maintenance of the physical and natural built environment, including works such as bridges, roads, canals, dams and buildings.
Careers
There is no one typical career path for civil engineers. Most engineering graduates start with jobs of low responsibility, and as they prove their competence, are given more and more responsible tasks, but within each subfield of civil engineering, and even within different segments of the market within each branch, the details of a career path can vary. In some fields and in some firms, entry-level engineers are put to work primarily monitoring construction in the field, serving as the "eyes and ears" of more senior design engineers; while in other areas, entry-level engineers end up performing the more routine tasks of analysis or design and interpretation. More senior engineers can move into doing more complex analysis or design work, or management of more complex design projects, or management of other engineers, or into specialized consulting, including forensic engineering.
Engineers are in high demand at banks, financial institutions and management consultancies because of their analytical skills.
Electrical engineering — sometimes referred to as electrical and electronic engineering — is an engineering field that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. The field now covers a range of sub-studies including power, electronics, control systems, signal processing and telecommunications.
I guess it is hard to conceive which one you will like without knowing the sort of maths and physics involved with them. All engineers will require a common base of applied mathematics, and in the University of Melbourne, all streams of engineering have a streamlined maths course for the first 2 years.
Physics-wise, I believe electrical engineering will focus largely on the core concepts of electro-magnetism, and probably a brief knowledge of materials is required to know about conductivity, and resistance losses. This means that study of heat flows would probably be required as well. In civil engineering, I suspect the concepts you learn will be mainly Newtonian mechanics, with study focused on material strength: density, tensile strength, etc.
