Electrical engineers are involved in channeling energy and electrical current into uses for humanity such as heating, lighting, home appliances, transportation, and communication. They are concerned with the processes of power generation, transmission, transformation, circuitry, control systems, and efficient utilization of energy and information. Electrical engineering is a very broad profession. You might work in: Circuits: the application of basic electrical elements – energy sources, resistors, inductors, capacitors, diodes, and transistors - as they are found interconnected in operational electrical networks. Communications-signal processing: the makeup of information-bearing signals, modulation systems, and detection techniques. Computer engineering: the design and/or applications of microprocessor systems, digital logic, digital-logic devices, digital design and automation, large computer systems, robot vision systems, artificial intelligence, and distributed processing. Controls: design and application of circuits and systems used to automatically monitor and regulate devices, machines, and systems for optimal performance in a variety of operations including flexible manufacturing. Electromagnetics: high-frequency waves, antennas, and microwave systems of various types for propagation and transmission of electrical signals through space or conductors. Optics and devices: light propagation, optical processing, fiber optics, opto-electronics, and solid-state devices which have application to telecommunications, computing, microscopy, lasers, sensing, and smart structures. Power: the design and application of motors, generators, transformers, distribution systems, high-voltage design methods, and the economic transmission of energy. Where do electrical engineers work: Many companies have a need for electrical engineers. You might work for Intel, Micron Technology, Hewlett Packard, Caterpillar, Motorola, Adtran, NCR, Sun, Guidant, Boeing, Tellabs, or the US Air Force.
