What happens to current density when two electrodes from one channel of an electrical stimulation unit are different sizes?

Question

Quizplus · Accepted Answer

When two electrodes from one channel of an electrical stimulation unit are different sizes, the current density will be greater under the smaller electrode. This is because current density is inversely proportional to the electrode area (current density = current/electrode area). Therefore, the smaller electrode, having a smaller surface area, will have a higher concentration of current passing through it compared to the larger electrode.
