where R is the resistance in series connection to the Randles circuit, then, the true potential is obtained by subtraction and the total current is plotted against the true potential. After such a correction, peak separations are expected to decrease, because higher currents correspond to a higher ohmic drop, which eventually results in decreased peak splitting, as shown with a red curve in Fig. , for different values of series resistance. However, after such compensation, the shape of the CV does not change, in contrast to hardware correction.
