This paper deals with the conductance calculation of the stabilised arc. For the design of the arc model it is supposed that the whole system is in the local thermodynamic equilibrium and the electrical arc is along the whole channel axial symmetrical. The aim of this paper is to propose the method of the conductance calculation of the stabilised arc and to apply the program for the electrical conductivity calculation created by the author. By using of the measured values of the arc current it can be calculated the arc voltage. The measuring was realized on the experimental arc heater for atmospheric pressure and the working gas was argon. The calculated conductance of the arc was compared with the conductance calculated from the measured values of the voltage and the current. Then the V-A characteristic of the arc was plotted and compared with the experimental V-A characteristic.
