either of two terminals of an electrically conducting system or cell; specifically, the uninsulated portion of a lead that is in direct contact with the body.
active electrode therapeutic electrode.
calomel electrode one capable of both collecting and giving up chloride ions in neutral or acidic aqueous media, consisting of mercury in contact with mercurous chloride; used as a reference electrode in pH measurements.
depolarizing electrode an electrode that has a resistance greater than that of the portion of the body enclosed in the circuit.
hydrogen electrode an electrode made by depositing platinum black on platinum and then allowing it to absorb hydrogen gas to saturation; used in determination of hydrogen ion concentration.
indifferent electrode one larger than a therapeutic electrode, dispersing electrical stimulation over a larger area.
point electrode an electrode having on one end a metallic point; used in applying current.
therapeutic electrode one smaller than an indifferent electrode, producing electrical stimulation in a concentrated area; called also active electrode.

cal·o·mel e·lec·trode

an electrode in which the wire is connected through a pool of mercury to a paste of mercurous chloride (Hg2Cl2, calomel) in a potassium chloride solution covered by additional potassium chloride solution; commonly used as a reference electrode.

calomel electrode

An electrode that develops a standard electric potential and is used to provide a reference voltage in the circuit for sensing electrodes. It is composed of an amalgam of mercury and mercury (I) chloride. It is used as a standard in determining the pH of fluids.
