Electrical engineering is a branch of engineering that focuses on the study of electricity, electronics, and electromagnetism It is a broad field that overlaps with many other engineering disciplines, including mechanical, civil, and chemical engineering Electrical engineers use their knowledge to design, test, install, and maintain electrical systems and equipment. They may also be involved in research and development, as well as designing new products.
1. High Voltage Engineering: High voltage engineering is the application of electrical power to systems and components that operate at a much higher voltage than the usual domestic voltage of 120V. It includes the design and installation of equipment, such as transformers and switchgear, as well as the transfer and distribution of power across large distances.
2. Automation and Robotics: Automation is the use of robots, machines, or processes to replace manual tasks. Automation is used in many industries, including manufacturing, mining, and logistics. Electrical engineers develop and implement automated systems, including sensors, servos, and control systems. They also design, test, and maintain robots and other computer-controlled machines.
3. Telecommunications: Telecommunications is the transmission of audio, video, and other data over long distances using wires, cables, or radio waves. Electrical engineers design, test, and maintain telecommunications systems, including internet networks, telephone networks, and satellite systems. They also study the propagation of signals over various media and develop new telecommunication technologies.
4. Power Electronics: Power electronics is the application of electronics and electric power to convert and control electrical energy. Electrical engineers design, test, and maintain power supplies and power converters for different types of applications, including renewable energy, medical equipment, and electric vehicles.
5. Computer Engineering: Computer engineering is the design, implementation, testing, and maintenance of hardware and software used in computing systems. Electrical engineers specialize in hardware design, including microprocessors, controllers, and FPGA circuits. They also work on embedded systems, such as microcontrollers, as well as computer networks and distributed systems.
