CG has various meanings in the Community category. Discover the full forms, definitions, and usage contexts of CG in Community.
An electrical circuit that uses a variety of conductors for a ground path. Ground conductors include wire, conduit, the metal of a building, or water pipes. Because so much of a building’s structure is grounded this way, a common ground is often electrically “noisy.” Therefore, an isolated ground is more suitable for computers.
