| 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 AMPERES REVS PER MINUTE FIG. 2. Page 4 | ||
