Unable to see change in current in lab 3?

Several groups have reported that the change in current in lab 3's task 1b during the discharge of the capacitor is impossible to measure, i.e. within the accuracy of the instruments and the noise in the data it just looks like the current is 100% unchanged for most of the discharge curve of the capacitor.

That may well be the case, in particular since we needed to change the value of the capacitance for the lab.

So if that is so, it is IMOPRTANT that you document in your report how you tried to compute the current and the change in current, show the data you used and the (noisy) results you have gotten, and describe why these results are not reliable enough to conclude that there is a change in current, and rather seem to indicate no change or too small a change to be detectable.

A new version of lab 3 has also been uploaded to the course webpage, that contains a link to the compendium regarding "output resistance".
