Find the temperature coefficient of metal X

  1. Jun 18, 2009 #1
    1. The problem statement, all variables and given/known data

    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




    2. Relevant equations



    3. The attempt at a solution

    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.
