The Phenomenon of Electroohmic Transformation

Abstract

Peculiarities of electric current distribution in an anisotropic electrically conductive medium are considered and dependences of its longitudinal and transverse components on geometrical factors are established. In the case of a rectangular plate of length a, height b, and width c, the selected crystallographic axes are located in the plane of the side face (a × b), and one of these axes is oriented at an angle α to the edge α. Application to the upper and lower end faces of the plate of some potential difference leads to the appearance of longitudinal and transverse components of the flowing electric current. This leads to the possibility of transforming the electric current magnitude. The methods of optimizing the transformation coefficient magnitude which is determined by both the magnitude of the anisotropy of the electrical conductivity of the plate material and the coefficient of its shape k = a/b. The design variants of anisotropic electrically conductive transformers are proposed. The use of this transformation effect makes it possible to expand the practical use of electroohmic phenomena. This principle of transformation will expand the areas of its use in metrology and measurement technology.

The method of turbulent transformation of energy

“…In Аshcheulov et al 1 for the first time, the possibility of the transformation effect in anisotropic electrically conductive unipolar media was shown. In this case, the device called anisotropic electroohmic transformer is a rectangular plate of length a , height b and width c , made of anisotropic single‐crystal or layered electrically conductive materials, characterized by linear volt‐ampere characteristics.…”

“…The method of transformation considered in References 1,3 is significantly different from the existing ones and has a number of relevant advantages and disadvantages.…”
