Hey I had a question on my quiz where it asked for the Resistance of aluminum at 600 deg C. But the formula rho-rho(i) = rho(i)a(T-T(i)) only finds the value of the resistivity at 600 deg C how do I convert it to resistance without more given info?
Question: A spool of aluminum wire has a resistance of 634 at 20o C. Find the resistance of the spool at 600o C
Alum = (rho(i)= 2.75x10^-8), (alpha = 4.4x10^-3)
My work
rho = (2.75x10^-8*4.4x10^-3*580)+(2.75x10^-8)
rho = (9.768x10^-8)
So I need to convert the resistivity to resistance from here but I just don't see how.
