For m O Signal Bell I Generator Negative Cathode Anode Positive Plating Tanl> Fig. 39.—Connections for Amperehour Meter example, if twelve dozen spoons were to be silver-plated and required 100 dwt. of silver, the indicatingpointer would be set at 100 on the dial, after whichthe large moving hand, operated by the mechanismof the meter, would be set at the zero point. As thecurrent passes through the meter, the large handmoves in a clockwise direction around the dial untilit reaches the pointer, in this case set at 100 dwt.,when contact is made against a pin in the adjustablepointer, thus operating through auxiliary leads to anelectric light or bell, as a signal. The external con-nections for the amperehour meter are shown inFig. 39 and can be easily understood. 78 The Modem Electroplater TANK RHEOSTAT As was explained in Chapter II, the quantity ofcurrent flowing in any one of a number of parallelcircuits is dependent upon the resistance of that.
