Solution
Based on propagation of uncertainty,
A practical application is an experiment in which one measures current, I, and voltage, V, on a resistor in order to determine the resistance, R, using Ohm's law, R = V / I. Given the measured variables with uncertainties, I ± σI and V ± σV, and neglecting their possible correlation, the uncertainty in the computed quantity, σR, is:
Another method would be to simply implement the tables in the spec sheets as equations in your code. When you get your V and I readings, calculate their inaccuracies, and divide as follows to find the worst case error:
Rmax = Vmax/Imin
Rmin = Vmin/Imax
Where
Vmax = Vreading + Vinaccuracy
Vmin = Vreading - Vinaccuracy
