ELECTRICAL ENGINEERS

  Electrical engineers conduct research; design, develop, test and oversee the development of electronic systems and the manufacture of electrical equipment and devices (electric motors; lighting and wiring in buildings; radar and navigation systems; communication systems; power generation, control and transmission devices). Electrical engineers also design the electrical systems of automobiles and aircraft. They traditionally have focused on the generation and supply of power, so they specialize in areas such as power systems engineering or electrical equipment manufacturing.

  Fundamental to the discipline (electrical engineering) are the sciences of physics and mathematics as these help to obtain both a qualitative and quantitative description of how systems will work. Today most engineering work involves the use of computers and it is commonplace to use computer-aided design programs when designing electrical systems. Besides, electrical engineers should know design techniques, tools and principles involved in production of precision technical plans, drawings and models.

  Perhaps the most important technical skills for electrical engineers are reflected in university programs, which emphasize strong numerical skills, computer literacy and the ability to understand the technical language and concepts that relate to electrical engineering. Knowledge of machines, including their designs, uses, repair and maintenance is also very important.

  For many engineers, technical work accounts for only a fraction of the work they do. A lot of time may also be spent on tasks such as discussing proposals with clients, preparing budgets and determining project schedules. Many senior engineers manage a team of technicians or other engineers and for this reason project management skills are significant too. Most engineering projects involve some form of documentation and strong written communication skills are therefore very valuable. Besides, electrical engineers have to keep up-to-date technically and apply new knowledge to their job.

  The workplaces of electrical engineers are just as varied as the types of work they do. Electrical engineers may be found in a fabrication plant, the offices of a consulting firm or on site at a mine. During their working life electrical engineers may find themselves supervising a wide range of individuals including scientists, electricians, computer programmers and other engineers.
