ELECTROLYTIC REGISTERING METER. 421increased, both in proportion to the strength of the current passingthrough the conductors. From sucli variation in the resistanceof either or both of the conductors forming the positiveand negative electrodes of the cell, the current energy expendedmay be readily computed. Figs. 229 and 230 illustrate twoforms of such a meter.In Fig. 229 G designates a direct-current generator. L L arethe conductors of the circuit extending therefrom. A is a tubeof glass, the ends of which are scaled, as by means of insulatingplugs or caps B B. c c' are two conductors extendingthrough the tube A, their ends passing out through the plugs B toFIG. 229.terminals thereon. These conductors may be corrugated orformed in other proper ways to offer the desired electrical resistance.K is a resistance connected in series witli the two conductorsc c', which by their free terminals are connected up incircuit with one of the conductors L.The method of using this device and computing by meansthereof the energy of the current will be readily understood.First, the resistances of the two conductors c c', respectively, areaccurately measured and noted. Then a known current is passedthrough the instrument for a -given time, and by a second measurementthe increase and diminution of the resistances of the twoconductors are respectively taken. From these data the constant is
