Propagation of Uncertainty in non-load voltage

Click For Summary

Discussion Overview

The discussion revolves around the propagation of uncertainty in the formula Es = Ex × (x + xo) / (xs + xo), particularly in the context of a circuit involving the potentiometer method. Participants seek to clarify the assumptions and distributions of the variables involved.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses difficulty in propagating uncertainty for the given formula, contrasting it with simpler formulas they can handle.
  • Another participant inquires about the assumptions regarding the distributions of the variables involved, questioning whether any are constant or non-random.
  • A participant clarifies that all variables are positive and none are constant, indicating a specific application in a circuit context.
  • There is a request for information about the distribution of the variables, suggesting a need for further clarification on this aspect.

Areas of Agreement / Disagreement

The discussion remains unresolved, with multiple competing views regarding the assumptions and distributions of the variables involved in the uncertainty propagation.

Contextual Notes

Limitations include the lack of specified distributions for the variables and the absence of detailed assumptions that could affect the uncertainty propagation process.

Need help propagating the uncertainty of Es = Ex ×(x+xo/xs+xo) . I understand all of the rules and can do it for a formula such as vo+ 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?
