Find the temperature coefficient of metal X

Click For Summary

Homework Help Overview

The discussion revolves around determining the temperature coefficient of metal X, focusing on the relationship between resistance and temperature. Participants are examining the applicability of certain formulas in this context.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster questions the validity of applying a specific formula for resistance based on temperature, given the non-linear relationship observed in a graph. They also inquire about the linearity of resistance with temperature and the constants involved in the equation.

Discussion Status

Some participants have provided insights regarding the behavior of resistance with temperature, suggesting that the original poster's approach may align with introductory course expectations. The discussion is ongoing, with no explicit consensus reached yet.

Contextual Notes

The graph referenced is not part of a measured lab assignment, and the inquiry stems from curiosity rather than a specific experimental requirement.

Homework Statement



Metal X
METALX.jpg

1) since the graph does not show that V is linearly related with I , is it right for me to apply the formula
R(50*C)=R(20*C) (1+ a lΔTl )
to find the temperature coefficient of metal X ?

2) R/Ω is linearly related with T/*C ?
If yes, will R=(dR/dT)T+c ?
Whereby dR/dT and c are constants that a fixed for the similar metal

For an introductory course I'd say this is what they would want you to use.

Is this graph part of a measured lab assignment?

the graph is not part of the measure lab assignment.
I ask this question simply because of curiosity.
Thank you for answering my question , your help is greatly appreciated.
