A Nichrome Wire and an Aluminum Wire,each with the Same $\rho$

Multiple Choice

A nichrome wire and an aluminum wire,each with the same initial resistance,have the same change in resistance when heated separately.( $\rho$ _Al = 2.82 *10 ^{- 8} $\Omega$ .m; $\alpha$ _Al = 3.9 *10 ^{- 3} / $\degree$ C; $\rho$ _nichrome = 1.50* 10 ^{- 6} $\Omega$ .m; $\alpha$ _nichrome = 0.40 * 10 ^{- 3} / $\degree$ C. ) The ratio of the temperature change of the nichrome wire to the temperature change of the aluminum wire is

A) 0.019.
B) 0.10.
C) 0.18.
D) 9.8.
E) 53.
