Electrical bonding is the practice of intentionally electrically connecting all exposed metal items not designed to carry electricity in a room or building as protection from electric shock. Bonding is also used to minimize electrical arcing between metal surfaces with electrical potential differences.
Equipment bonding conductors or equipment ground conductors (EGC) provide a low-impedance path between normally non-current-carrying metallic parts of equipment and one of the conductors of that electrical system's source. If any exposed metal part should become energized (fault), such as by a frayed or damaged insulator, it creates a short ...
In electrical engineering, ground and neutral (earth and neutral) are circuit conductors used in alternating current (AC) electrical systems. The neutral conductor receives and returns alternating current to the supply during normal operation of the circuit; to limit the effects of leakage current from higher-voltage systems, the neutral ...
A common example is two electrical devices each connected to a mains power outlet by a three-conductor cable and plug containing a protective ground conductor for safety. When signal cables are connected between both devices, the shield of the signal cable is typically connected to the grounded chassis of both devices. This forms a closed loop ...
Bonding jumpers may be installed wherever metal parts are free to move on a hinge or bearing. This is done for electrical safety grounding, static electricity protection, and may also be useful for control of electromagnetic interference. For example, a control panel door may have a bonding jumper across the hinges so that the metal door is ...

Along the same lines, most electronic effects (capacitance, electrical conductance, electric-field screening) involve the physics of electrons passing through surfaces and/or near interfaces. The full description of these effects, in a band structure picture, requires at least a rudimentary model of electron-electron interactions (see space ...
