Solution for "Resistance Measurements"
Especially the error-calculation is a little bit tricking and honestly, if you argue correctly even other solutions are thinkable. I really recommend for any error-calculation to write down, why you choose the way you did.
For this task the points would be distributed in a way, that the "creative" tasks c) & d) would get roughly 40% of the points, and the rest the remaining 50% with probably a little more on a than on b) and e)
Please be careful for this solution and part e). In the quesiton it is asked abou the number of digits required to resolve the 5% tolerance. In the solution the total voltage is calculated to represent 320 digits. But then of course you need to calculate the 5% tolerance, which is 320*0.05=16 digits. I am sorry for the confusion!
