Electrical engineering History Outline Glossary Category Portal v t e Some electrical engineers design complex power systems on a macroscopic level. Electrical engineers also design microscopic electronic devices and electronic circuitry, which achieved the record setting length of 1 nanometer for a single logic gate. [1] Electrical engineering is a professional engineering discipline that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an identifiable occupation in the later half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use. Subsequently, broadcasting and recording media made electronics part of daily life. The invention of the transistor, and later the integrated circuit, brought down the cost of elec...
