Previous Year Question
The armature winding symbol mainly represents which electrical property?
Correct answer: B
Explanation
An armature winding is made of conducting turns wound around an iron magnetic structure. Electrically it has winding resistance and appreciable inductance, so its practical model includes R and L.
Step-by-step solution
Correct Answer
B — Resistance and inductance
Explanation
An armature winding is made of conducting turns wound around an iron magnetic structure. Electrically it has winding resistance and appreciable inductance, so its practical model includes R and L.
Key Concept
Armature Resistance and Inductance
Exam Point
A real winding is not pure L: it has copper resistance + inductance.
Exam tip
A real winding is not pure L: it has copper resistance + inductance.
Quick method
A real winding is not pure L: it has copper resistance + inductance.
