o -17- values the difference in voltage is lens than one volt,butwhen the high speeds and current are reached there is twice thedifference in voltage,which would tend to prevent the currentover a constant resistance load from rising.The currentincreases less rapidly as the speed increases and the curvebegins to bend toward the axis as the speed reaches the highvalues which is a desirable condition.By plotting the speedvoltage curves of the two tests on the same sheet the comparisonbecomes more evident,( curve No 8,page 18 ).
