Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use. It now covers a wide range of subfields including electronics, digital computers, power engineering, telecommunications, control systems, RF engineering, and signal processing.
Electrical engineers are instrumental in revolutionizing the lives of modern man. They are required by the industries manufacturing all the household and office appliances like refrigerators, televisions, computer, microwaves and what not. In our age of satellite-transmitted television and transcontinental computer networks, these engineers are high in demand. Electrical engineers also find employment in atomic power plants, hydroelectric power plants as well as thermal power plants.
