Question 529Electricity & Electronics - QMED

The correct answer is B) Under compounded. A compound-wound DC generator with a higher voltage at no load than at full load is considered under compounded. This means that the series winding, which is designed to boost the voltage at full load, is not strong enough to fully compensate for the voltage drop caused by the armature reaction. As a result, the terminal voltage decreases as the load increases, resulting in a higher voltage at no load compared to full load. The other options are incorrect because: A) Terminal compounded refers to a generator with a series winding designed to maintain a constant terminal voltage regardless of load. C) Flat compounded refers to a generator with a series winding designed to maintain a constant terminal voltage from no load to full load. D) Over compounded refers to a generator with a series winding designed to increase the terminal voltage as the load increases.
