IL = Load Current, then the relation between these currents for a DC series generator is

• A. IL ÷ Ise ÷ Ia
• B. IL = Ise = Ia
• C. IL = Ise + Ia
• D. IL ÷ Ise = Ia

Answer: (B)

When the field winding is connected in series with the armature winding while supplying the load then the generator is called a  series generator.
Current Relations
As all armature, field, and load are in series they carry the same current.
IL = Ise = Ia
