The winding W is thus magne-tized and holds the iron plunger in this position until the charging circuit is actually interruptedor the voltage of the generator falls below the battery. In event of either happening, theplunger drops downward, breaking the circuit. 72. The Ampere-Hour particularly useful instrumentfor denoting the state of chargeor discharge of a storage batteryis the ampere-hour meter, which inessence is a specially constructedsmall motor connected in serieswith the charge and discharge of astorage battery. The motor is geared to a pointermoving over a dial calibrated inampere hours, and therefore per-.
