In this article a solution is given of differential equation representing the energy of the cylindrical part of an unstationary arc. Universal functions of conductance, radiation and enthalpy are introduced on the basis of the physical model of two-layer arc. Similarity conditions of arcs in gas of the same chemical composition are specified. The influence of the conical part and of external disturbances on the model of dynamie arc is analysed. The transmittance of the arc has Been obtained by local linearization of its characteristics. The relations holding between the arc transmittance parameters (time constant and coefficients) and the parameters of plasmagenic gas and of heat exchange coefficients are also given
