DC generators have several characteristics, including: Internal characteristics: These characteristics show the relationship between the generated EMF and the armature current. External characteristics: These characteristics show the relationship between the terminal voltage and the load current. Magnetization characteristics: These characteristics show the variation of generating voltage with field current at a constant speed. Open circuit characteristics: These characteristics show the relationship between the generated EMF at no-load and the field current. Speed: The speed of a DC...
