The adequacy of power approximation of volt-ampere 
characteristics of a dc electric-arc generator is estimated. Using 
Fisher's ratio for the variances of the inadequacy and random error, 
it is shown that this approximation is acceptable. It is also shown 
that the power source has a slight effect on the characteristics of 
the arc.
