My material shows the current response of CV is roughly 80 microamps, whereas the current response of DPV is approximately 20 to 25 microamps. Why is this so? Why is the current response of the DPV lower than that of the CV? Is it expected that the DPV will produce the same current response as seen on the CV or not? What causes the DPV to give a current response of 20 to 25 microamps when the CV's current response reaches 110 microamps? I've attached two images to help you understand.
