Electrical and electronics are both sub branch in electrical engineering. Electrical engineers, design, develop, test, and supervise the manufacturing of electrical equipment, such as electric motors, radar and navigation systems, communications systems, or power generation equipment. Electrical engineers also design the electrical system of automobiles and aircraft.
CAD tools help electrical Engineers to design power plant installation drawings, schematic circuit diagrams, Panel diagram, PLC design, Mechatronics Design, Connector diagrams and to generate reports of various designs.
