ground
reference point in an electrical circuit from which voltages are measured
ground and neutral
in electrical mains wiring, a pair of conductors connected to earth but with different purposes
functional earth
specific notion of electrical ground, used as part of a device's operation and not as a protective system
ground in electronics
common ground network in electronic circuits and systems, which serves as a zero voltage reference
chassis ground
electrical ground created by connecting the circuit to a conductive enclosure, treating the enclosure's potential as the reference voltage
neutral conductor
in mains electrical wiring, a conductor used as a common return path for electric current
floating ground
reference point for electrical potential in a circuit which is galvanically isolated from actual earth ground
