The analytical and numerical dependences of the total transverse current on an electric field, the normal component of a magnetic field and the ion and electron temperatures are obtained using analytical approximation of numerical results provided by a self-consistent model of the magnetospheric thin sheet. The dependence of current on the parameters $\varepsilon$, $T_i$, $b_n$ is shown to be nonlinear. The relative contributions of different plasma components into the total current are estimated.
