USCG Exam PracticeMotors and generators
Which type of DC generator is LEAST suitable for use as a general power source due to inherently unstable terminal voltage?
- A. Shunt-wound generator
- B. Flat-compounded generator
- ✓ Series-wound generatorCorrect
- D. Over-compounded generator
Why C is correct
NEETS Mod. 5 §1-3 states that in a series-wound generator the field is in series with the armature and load, so field strength and voltage rise with load current, making voltage unstable; this type is rarely used for power. Shunt, flat-compounded, and over-compounded generators all provide reasonably stable terminal voltage.
