What problems may result by using an electrode at too low a current and too high of a current?

Using an electrode at too low a current can lead to inadequate electrochemical reactions, resulting in poor signal quality or insufficient output, which may hinder performance in applications like electrolysis or sensors. Conversely, applying too high a current can cause overheating, leading to electrode damage, increased wear, or even degradation of the electrolyte, potentially compromising the system's integrity and efficiency. Both extremes can negatively affect the overall effectiveness and lifespan of the electrode.
