THE SMITH CONSTANT CURRENT DYNAMO.

Fig. 2.
A - Curve showing Current to Line
B - Curve showing Current between a Main and an Auxiliary Brush
C - Speed at which dynamo starts to supply Current to the line.
D - Point at which Current in Resistances equals Current to Line.
E - Speed at which Auxiliary Brushes are shorted. Current in Resistances=0
F - Speed for full Output to Line. Current in Resistances = 1/2 Main Current
