| -4- Contd. the same dynamo speed after operation, the output fell to 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 volts ampere characteristic in obtaining these curves.
