Electrical engineers play an important role in the design, implementation and management of electrical and electronic equipment of all sizes, such as electronic computers that can handle billions of instructions per second to substations, telephones and computers. Electrical engineers also design electrical systems for high-tech applications, such as spacecraft, satellites and power.
Electrical engineering is not only a central discipline in communication, especially in civil aviation and deep space network, but also plays an important role in medical field, such as bionic ears and eyes, which are used to repair the path from the environment to the brain, pacemakers and life support systems. With the increasing contact and the development of radio, the discipline of electrical engineering has become perfect.
