    1. The problem statement, all variables and given/known data
    Initially, copper wire is 20oC then raises the temperature of the wire casing the resistivity up 12%, find the temperature at the final.

    2. Relevant equations
    R=Rref[1+α(T-Tref)]

    3. The attempt at a solution
    I am completely confused with this mathematics problem,Stucking with the final resistivity ( R ) in the equation

    If the initial resistance is 10 Ohm, what is the final resistance?
    If the initial resistance is R0, what is the final resistance?
