A material's resistivity varies with
A) its length
B) its cross-sectional area
C) its temperature
D) the shape of its cross-section

Question

Quizplus · Accepted Answer

Resistivity is a property of the material and is defined as the resistance of the material per unit length and cross-sectional area. However, it is also dependent on the temperature of the material, which can change its atomic structure, and therefore affect its resistance. Length, cross-sectional area, and shape of the cross-section all affect the resistance of the material, but not the resistivity.
