In a CV experiment, what happens after linearly ramping to the 'switching' potential? The potential remains constant for the rest of the experiment. The current is turned off and the electrodes are removed. The potential linearly ramps back to the starting potential. The potential immediately doubles.

Scanning electrochemical microscopy was used to study the lifetime of guanosine radical, which was generated by one-electron oxidation of guanosine. In the experiments, guanosine was oxidized at an SECM tip ultramicroelectrode and the cation radical was reduced at a conductive substrate. At the tip–substrate distance of 0.3 µm, the tip current was –1.1*10–9 A and the substrate current was 1.1*10–11 A. Calculate the percentage of tip-generated guanosine radical molecules that were detected at the substrate.
