Question 9 • Physical Science

Resistance depends on which three properties of a wire? Color and texture are not directly related to a wire’s resistance.

Answer
A
color, thickness, texture
B
temperature, color, texture
C
length, texture, temperature
D
thickness, length, temperature

Explanation

A wire’s resistance depends on its length, its thickness (cross-sectional area), and its temperature. A longer wire has greater resistance, while a thicker wire generally has less resistance; temperature also affects resistance. Color and texture do not determine electrical resistance, so the correct choice is “thickness, length, temperature.”
