Two Forms of Ohm's Law on Anisotropic Basic Electronic Elements
Sun Bin-xiang · Journal of Circuits and Systems · 2003
Owing to conducting anisotropy of the anisotropic resistance element,the current density direction doesn't coincide with the electric field intensity direction. Thus, Ohm's law is of two forms: one in the current density direction and the other in the electric field intensity direction. There exist a resistance tensor and a conductance tensor respectively, both in the form of second order. Calculating formulae for both tensors are accordingly given. Analysis shows that two forms of Ohm's law on the anisotropic resistance element are approximate.
