Question

Define ohm's law and establish a relationship between the resistivity and electric field in a conductor

Answer 1

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. ... Ohm's law is an empirical relation which accurately describes the conductivity of the vast majority of electrically conductive materials over many orders of magnitude of current.

I ∝ V

I = V ⇒ V = IR
