Knowra Electrical engineering Electrical engineering Electrical engineering is the branch of engineering concerned with designing and applying systems that use electricity, electronics, and electromagnetism.
Circuit theory : The study of voltage, current, and power in interconnected electrical components. It provides the core methods for analyzing electrical networks.
Electric power system : The network of generators, transmission lines, substations, and loads that supplies electrical energy. Power engineering designs and operates this interconnected infrastructure.
Electrical telegraph : A communication system that sends coded messages over wires using electrical signals. The telegraph demonstrated electricity's practical value for long-distance communication.
Mechanical engineering : The branch of engineering concerned with the design and analysis of mechanical systems and machines. It focuses on forces, motion, and physical mechanisms rather than electrical systems.
Electromagnetism : The physical interaction between electric charges, electric fields, and magnetic fields. It underlies motors, generators, antennas, and many electrical devices.
Telecommunications : The transmission of information over distance through wired, wireless, or optical channels. Communications engineering builds the systems that carry voice and data.
Faraday's law of induction : The principle that a changing magnetic flux through a circuit induces an electromotive force. Induction enabled practical generators and helped establish electrical power engineering.
Computer engineering : The discipline that integrates electrical engineering and computer science to design computer hardware and systems. It overlaps with electrical engineering but centers more directly on computing hardware.
Semiconductor : A material whose electrical conductivity can be controlled by composition, temperature, or applied fields. Semiconductors make modern electronic components possible.
Microelectronics : The design and fabrication of electronic components and circuits at microscopic scales. It applies electrical engineering to integrated circuits and compact devices.
