What is the effect of armature reaction in DC generator?
Understand the Problem
The question asks about the effect of armature reaction in a DC generator, specifically what impact it has on output voltage.
Answer
Output voltage decreases.
The final answer is B: Output voltage decreases.
Answer for screen readers
The final answer is B: Output voltage decreases.
More Information
Armature reaction in a DC generator distorts and weakens the main magnetic flux, leading to a decrease in the generated voltage. This is due to the interaction between the armature's magnetic field and the main magnetic field.
Tips
Commonly, people may mistakenly think the voltage remains unchanged or increases. Understanding magnetic field interactions helps clarify this.
