What is electrical engineering?
Electrical engineering is the engineering discipline that studies how electrical energy and electrical signals are generated, transmitted, controlled, measured, and used.
Electrical engineers work with circuits, motors, power systems, electronics, sensors, embedded devices, communication networks, automation systems, and control systems. The field connects directly to modern infrastructure, renewable energy, manufacturing, robotics, consumer electronics, telecommunications, transportation, and computing hardware.
Because electrical engineering is broad, it is usually divided into major focus areas such as electronics engineering, power systems engineering, control systems engineering, and communications engineering. Each branch uses math, physics, circuit theory, signal analysis, and engineering design to solve different types of problems.
