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. (ρAl = 2.82 × 10⁻⁸ Ω ⋅ m; αAl = 3.9 × 10⁻³ / °C; ρnichrome = 1.50 × 10−6 Ω ⋅ m; αnichrome = 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.
