INDUSTRIAL APPLICATIONS. 



Let i\, / 2 , . . . t n be the currents in the resistances x lt x 2 ,... x n . 

 If all the resistances are respectively equal to each other, we have, 

 from symmetry, at an equal distance from the ends, 



The shunt currents diminish from the ends of the principal 

 conductors to the middle, for we have 



aa p + xip = 



Now, the difference fi p - - is positive as long as / >- . In these 



conditions the different organs would receive in pairs the same 

 energy. The benefit, however, of this arrangement is not great 

 enough to compensate for its practical inconveniences. 



In both cases the suppression of one of the shunted parts has 

 the effect of increasing the general current. This inconvenience 

 can be counteracted, either by a regulator of the current, which 

 brings variable resistances into the circuit, or by the aid of an 

 auxiliary current shunted in the circuit, and which keeps constant
