    • n Electrode (Elec) a conducting object by which electricity is conveyed into or from a solution or other non-metallic conducting medium; esp., the ends of the wires or conductors, leading from source of electricity, and terminating in the medium traversed by the current.Electrodes may be specially designed or made of a special material for particular purposes, as for example silver electrodes used in electroplating.

And fix it on your whirling table;
Place the electrodes firm and sure
As near the axis as you’re able,
And soon you’ll learn the way to work it,
With galvanometer in circuit.
