When electrodes are used to record the electrocardiogram, an electrolyte gel is usually put between them and the surface of the

klemol [59]

Answer:

The equivalent circuit for the electrode while the electrolyte gel is fresh

From the uploaded diagram the part A is the electrolyte, the part part B is the electrolyte gel when is fresh and the part C is the surface of the skin

Now as the electrolyte gel start to dry out the resistance $R_s$ of the gel begins to increase and this starts to limit the flow of current . Now when the gel is then completely dried out the resistance of the gel $R_s$ then increases to infinity and this in turn cut off flow of current.
