A study was made of the features of electric current transformation by an anisotropic electrically conductive medium characterized by different types of conductivity (p- and n-types) in selected crystallographic directions under ohmic contact conditions. It has been established that in the case of an external sinusoidal electric current flowing through a device based on a rectangular plate of the above mentioned anisotropic material, electric current vortices occur in its bulk. Based on the analysis of the function m (K, α) (case | m |> 1), which determines the transformation coefficient of the device, a conclusion is made about the energy interaction between the bulk of the anisotropic plate and the external medium.. Studies have shown that the use of anisotropic electrically conductive bipolar material leads to a significant higher (m> 1) or lower (m <-1) value of the transformation coefficient m than in the case of unipolar anisotropic electrically conductive materialss. The phenomenon of electroohmic transformation is caused by the appearance of electric field vortices which are characterized by turbulent flow represented by the expression r, where ω is a circular frequency of vortex rotation, and signs «+» and «–» denote the direction of its rotation and are determined by the value of the anisotropy coefficient K=σ11/σ22. Such electric vortices with a turbulent flow are an efficient mechanism of pumping energy between the external medium and, in our case, the anisotropic plate of the device. It should be noted that in some cases there is an anomalous value of the abovementioned coefficient. The application of the considered method of electric current transformation with the help of the proposed devices, which are based on a plate made of anisotropic electrically conductive material, significantly expands the field of alternative electricity and other related fields of science and technology.
