Electrical Engineering is an extremely exciting field of endeavor. 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. My opinion has always been that electrical engineers can do everything.
