What is the effect of using a low electrode impedance?

A low electrode impedance enhances comfort during stimulation for several reasons. When impedance is low, it allows for a greater flow of electrical current at a lower voltage. This results in a more tolerable and comfortable sensation during electrical stimulation. High impedance, on the other hand, can lead to higher voltages being necessary to achieve the desired current levels, which may cause discomfort or pain.

Additionally, lower impedance provides better conductivity and minimizes the resistance the current has to overcome, allowing for smoother and more efficient transmission of the stimulating currents. This contributes to a more pleasant experience for the recipient, as the sensation felt during electrical stimulation can be more controlled and less jarring when the impedance is kept low.

While there are reasons why the other options might seem relevant, they do not accurately reflect the primary benefits associated with low electrode impedance in practical applications.
