Relationship between resistivity and Mathiessen's Rule

  1. Jun 10, 2012 #1
    This question has bogged me down for hours. Please help.

    An alloy of metals is found to have a resistivity of 1.2e-6Ωm at 300K. When it is heated to a temperature of 973K, the resistivity is found to increase by 10 per cent. Assuming Mathiessen's rule to hold good for the alloy, find its resistivity due to inpurities scattering alone.

    Welcome to PF!

    Hi Lindoc! Welcome to PF! :wink:

    Show us what you've tried, and where you're stuck, and then we'll know how to help! :smile:

    (Also, state Mathiessen's rule so we don't have to look it up! :redface:)
