Page 3 PROBLEM 2. (20 points) in the lectures, two forms of Ohm's Law - a "microscopic version" and a "macroscopic version" - were discussed. However, electrical engineers will sometimes talk about a third form of Ohm's Law called a "circuit version" or "field version": . 1 -SE.dl R= IS E da| where o is the electrical resistivity for the conductor being studied (which is assumed to be ohmic). Starting with the macroscopic version of Ohm's Law R = V/1, use the microscopic version of Ohm's Law along with the definition of the electric potential V to derive this "circuit version" of Ohm's Law.
