The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices, such as cell phones and media players, as well as circuits in vehicles, may be spoken of as having a "ground" or chassis ground connection without any actual connection to the Earth, despite "common" being ...
The cable has a ground or shield conductor which is connected to the chassis ground of each component. The driver amplifier in component 1 (left) applies signal V 1 between the signal and ground conductors of the cable. At the destination end (right), the signal and ground conductors are connected to a differential amplifier.
A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. [1] Examples include electronic instruments and motor vehicles. Usages
Floating grounds can be dangerous if they are caused by failure to properly ground equipment that was designed to require grounding because the chassis can be at a very different potential from that of any nearby organisms, who then get an electric shock upon touching it. Live chassis TVs, also known as hot chassis, where the set's ground is ...
Multiple Un-referenced End-Circuits with a single return – isolation between several input signals and circuit chassis/common ground. Subsystem with Isolated Common – isolation between signal input and common ground. Common Chassis Ground – isolation between circuit common and chassis (chassis grounded).
A ground connection that is missing or of inadequate capacity may not provide the protective functions as intended during a fault in the connected equipment. Extra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage.
(The phrase "ground, live, return", corresponding to "X, L, R", is often offered as a memory aid, although the second signal wire is not a "return" in the case of differential signaling) On TRS phone plugs, the tip is signal/non-inverting, the ring is return/inverting, and the sleeve is chassis ground.
