ls. The variation incurrent that may be produced by such a rheostat will dependupon the relation between the resistance of the circuit inwhich the rheostat is connected and its own total resistance.Such rheostats, as a rule, have rather a small current-tarrying capacity. A rheostat composed of a… … Fig. 233 DISTRIBUTION AND OPERATION 275 a small handle shown in the figure. The resistance of thisrheostat is, as a rule, rather low, but its current-carryingcapacity is quite large. Itoperates very satisfactorilyin low voltage circuits andthe variations in its resist-ance can be made verygradual.…
