In DC generator, lap winding is used in
A. high current and low voltage applications.
B. high voltage and low current applications.
C. where constant speed is required.
D. where greater load is connected.
Answer: A
Share your understanding of this question with the correct explanation.
In a DC generator, lap winding is commonly used in high current and low voltage applications.
Lap winding is a type of armature winding configuration in which multiple parallel paths are formed by connecting the coils in a lap-like manner. The number of parallel paths is equal to the number of poles in the machine. Each coil spans across several commutator segments and overlaps adjacent coils.
Lap winding is suitable for applications where high currents are required because it allows for better current distribution and lower resistance. It is commonly used in DC generators that need to deliver high currents at low voltages, such as in industrial applications or electric traction systems.
Therefore, option A, “high current and low voltage applications,” is the correct answer.
