ground
  • The surface of the planet earth, especially the land portion.
  • The earth, which is arbitrarily considered to have an electric potential of zero. Also, a conducting path to the earth. For instance, a path which leads to a large copper plate buried in moist soil. Also, a conducting object, such as a wire, leading to the earth. Its abbreviation is gnd. Also called electrical ground (1), or earth (2).
  • A large conducting body whose electric potential is arbitrarily considered to be zero. Also, a conducting path to such a body. Also, a conducting object, such as a wire, leading to such a conducting body. Also called electrical ground (2), or earth (3). Its abbreviation is gnd.
  • Within a circuit, a point which is at zero potential with respect to a ground (2), or ground (3). Also called electrical ground (3), or earth (4).
  • To connect to a ground (2), ground (3), or ground (4). A path to a ground may be intentional or accidental. Also called electrical ground (4), or earth (5).
