For an ohmic substance, the resistivity depends on:
A)the electric field
B)the potential difference
C)the current density
D)the electron mean free time
E)the cross-sectional area of the sample

Question

Quizplus · Accepted Answer

The resistivity of an ohmic substance is influenced by the electron mean free time, as it affects how easily electrons can move through the material, thus impacting its resistance. Other options like electric field, potential difference, current density, and cross-sectional area affect resistance or current flow but do not directly affect the material's inherent resistivity.
