A second set of curvesfor a similar condenser formed to 100 volts and operated on a 66-voltbattery, maximum 75, are shown in Fig. 13. THE ALUMINUM ELECTROLYTIC CONDENSER 59 It will be noted that the capacities of the condensers decrease withincreasing frequency. While there is a slight decrease in the unit-area capacity of films that accompanies a rise of frequency ^ thisdrooping characteristic is due principally to the corrugated shape ofthe plates on which the film is formed. The resistance through theelectrolyte from the negative electrode to the film at the mouth of aU shaped corrugation, is less than that to the portion of the filmat th
