24.4a : Confirm that equation has the same units on both sides of equal sign 24.7 : confirm that equation has units of energy divided by time
rrent density J is the current per it area at a point in a material. - J = GE o is the conductivity, a property of the material. E is the electric field at the point where we're evaluating 7. (Ohm's law, microscopic version) The microscopic version relates electrical quantities at each individual point. (24.4a)
