| AC.74. -4- Contd. just above zero. On a discharged Exide battery the full dynamo output was reached with a good margin before operating the controller. A series of curves (attached) was also taken on a standard dynamo, shewing the effects of various resistances in the field circuit. These fairly well represent what would be obtained on a car with the battery fully charged. The dynamo was run on our scheduled volt-ampere characteristic in obtaining these curves. EFC {E.
