Propagation of Uncertainty in non-load voltage

[beny748]

Need help propagating the uncertainty of E_s = E_x ×(x+x_o/x_s+x_o) . I understand all of the rules and can do it for a formula such as v_o+ at. But I am having trouble with the (A+B)(/A+C).

Hey beny748 and welcome to the forums.

What are the assumptions for the distributions of your variables? Are any constant (i.e. non-random)?

Thanks Chiro!

All are positive and none are constant. The problem involves a circuit, in particular the potentiometer method. I felt it was unnecessary information.

Also.. I apologize, it looks like I placed this in the wrong thread.

What distribution do they have?
