Electrical engineering is a specialized branch of engineering focused on the design, study, and practical application of systems that utilize electricity, electronics, and electromagnetism. Professionals in this field work with a vast array of equipment and devices, ranging from microscopic integrated circuits to massive power generation systems that support modern infrastructure.
The discipline emerged as a distinct professional field during the latter half of the 19th century. This growth was primarily driven by the rapid commercialization of transformative technologies such as the electric telegraph, the telephone, and the widespread implementation of electrical power distribution systems.
