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. (ρ_Al = 2.82 × 10−⁸ Ω ⋅ m; α_Al = 3.9 × 10−³ / °C; ρ_nichrome = 1.50 × 10−⁶ Ω ⋅ m; α_nichrome = 0.40 × 10−³ / °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.
