ground electrode

[′grau̇nd i¦lek‚trōd]
(electricity)
A conductor buried in the ground, used to maintain conductors connected to it at ground potential and dissipate current conducted to it into the earth, or to provide a return path for electric current in a direct-current power transmission system. Also known as earth electrode; grounding electrode.

Two electrodes were introduced in the model; the one representing the handset has 5 x 6 voxel faces and is located in a x-y plane on top of the tooth model (in contact with the enamel), the other representing the current collector (ground electrode) has 30 x 30 voxel faces and is in a y-z plane in contact with the gum in proximity of the enamel.
By changing the potentials applied on the CNTs and the ground electrode, the depth of the curved electric field profile can be varied.

A ground electrode was attached to a downstream collimator within the flume.
In an intensive care setting where other electrical devices are used, everything should be plugged into the same power column thus creating a common ground.[13] In the operating room, patients have a large grounding pad placed which negates the need for an EEG ground electrode.
