Ohm’s Law in terms of the applied potential. But we canre-express the potential as the integral of the electric fieldalong some path. We can also re-express electrical resistance interms of conductivity, length, and cross-section. Use theserelationships to write Ohm’s Law in terms of the electric field andthe current density.  What physical parameter does alinear fit to the slope of the resistor current graph represent?Why is a similar graphical analysis of the diode current notappropriate?
