2. Ground (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_(electricity)

   Strictly speaking, the terms grounding or earthing are meant to refer to an electrical connection to ground/earth. Bonding is the practice of intentionally electrically connecting metallic items not designed to carry electricity. This brings all the bonded items to the same electrical potential as a protection from electrical shock.

3. Ground loop (electricity) - Wikipedia

   en.wikipedia.org/wiki/Ground_loop_(electricity)

   A ground loop is caused by the interconnection of electrical devices that results in multiple paths to ground, thereby forming closed conductive loops through the ground connections. 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 ...

4. Ground and neutral - Wikipedia

   en.wikipedia.org/wiki/Ground_and_neutral

   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 ...

5. Earth battery - Wikipedia

   en.wikipedia.org/wiki/Earth_battery

   However, in the process of installing long telegraph wires, engineers discovered that there were electrical potential differences between most pairs of telegraph stations, resulting from natural electrical currents (called telluric currents [4]) flowing through the ground. Some early experimenters did recognize that these currents were, in fact ...

6. Floating ground - Wikipedia

   en.wikipedia.org/wiki/Floating_ground

   Electrical equipment may be designed with a floating ground for one of several reasons. One is safety. For example, a low-voltage DC power supply, such as a mobile phone charger, is connected to the mains through a transformer of one type or another, and there is no direct electrical connection between the current return path on the low-voltage side and physical ground (earth).

7. Earth-return telegraph - Wikipedia

   en.wikipedia.org/wiki/Earth-return_telegraph

   A telegraph line between two telegraph offices, like all electrical circuits, requires two conductors to form a complete circuit. This usually means two distinct metal wires in the circuit, but in the earth-return circuit one of these is replaced by connections to earth (also called ground) to complete the circuit. Connection to earth is made ...

8. Grounding - Wikipedia

   en.wikipedia.org/wiki/Grounding

   Grounding, a strategy for coping with stress or other negative emotions; Grounding in communication, the collection of mutual knowledge, beliefs, and assumptions; "common ground" Ground (electricity), a common return path for electric current; Symbol grounding problem, a problem in cognition and artificial intelligence

9. Telluric current - Wikipedia

   en.wikipedia.org/wiki/Telluric_current

   In industrial prospecting activity that uses the telluric current method, electrodes are properly located on the ground to sense the voltage difference between locations caused by the oscillatory telluric currents. [7] [8] It is recognized that a low frequency window (LFW) exists when telluric currents pass through the Earth's substrata.
