A Nichrome Wire and an Aluminum Wire, Each with the Same

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; $\alpha$ 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.
