Electrical engineers work with signal at frequencies from zero to beyond the optical range, and they use tools such as computers, advanced mathematics, and wire cutters. Electrical engineers are thinkers and doers. Strictly speaking, Electrical Engineering is not just a single field, but a collection of many fields fused into one unified discipline. It is by far the most dynamic and most varied of all fields in engineering. The best way to find out what Electrical Engineering is to see what electrical engineers do and form your own definition.
Most electrical engineers believe they can do everything.
Think for a second about what kind of things in our everyday lives might have needed an electrical engineer. Everything from the computer you are using right now to the lights in your room is a result of something an electrical engineer has worked on.
