Electrical engineering is a field of engineering that deals with the study of electricity and how it is used in different applications. Electrical engineers create, design, test and maintain electrical systems. Electrical engineers use their knowledge to create things like computers and cell phones, design motors and generators for power plants, and build robots for factories. Electrical engineers also work with electronics, which are circuits that control the flow of electricity. They use this to create things like sensing systems, communication systems, and autonomous systems.
