Abstract
The mathematical model describing the axisymmetric electromagnetic field and the constriction resistance of the semispace with AC electrical current passing through a ring-shaped contact is presented. It is based on the system of the Maxwell equations with the special boundary conditions. The analytical formulas for the electric and magnetic fields are obtained. The asymptotic expression for the constriction resistance is found and the corresponding expression for the DC current may be derived from this general expression as a special case. Comparison of this expression with the well known classical formula shows very good approximation.
