Microscopic Ohm's Law and Non-Ohmic Materials
For a non-ohmic material, how does the relationship describe its deviation from Ohm’s law?
A
It indicates that Ohm’s law applies universally to all types of materials, including semiconductors
B
It suggests that electric field is inversely proportional to current density in all materials
C
It proves that the electric field is always perpendicular to the current density vector
D
It implies that resistivity can vary with current density, contradicting Ohm’s law’s assumption of constant resistance
