Electrical devices or electric devices are tool that functionally rely on electric energy (AC or direct current) to operate their core parts (, , electric light, rechargeable batteries, control electronics). They can be contrasted with traditional mechanical devices which depend on different power sources like or human physical strength. Electronics are a specialized kind of electrical devices in which electric power is predominantly used for data processing rather than the generation of mechanical forces. To better differentiate between both classes, electric devices that emphasize physical work are also called electromechanics. Mechatronics accentuates the intersection of both fields.
Together, electronic and electric devices, their development, maintenance, and power supply comprise the subject of electrical engineering.
The majority of electric devices in households is stationary and — due to their considerable power consumption — relies on electrical installation, especially instead of small electric generators, batteries, rechargeable or not.
Due to their dependence on electric power sources, in general well-evolved , electric devices and their power consumption pattern have moved into the focus of smart metering.
More specifically, electrical equipment refers to the individual components of an electrical distribution system. These components may involve:
