Architecture Quiz for Grade 1 Students

What are the two types of armature windings?

• Round winding and square winding

• Clockwise winding and counterclockwise winding

• Lap winding and wave winding

• Single winding and double winding

How is lap winding construction different from wave winding construction?

• Lap winding connects the armature coils in series, while wave winding connects the armature coils in parallel.

• Lap winding and wave winding are the same.

• Lap winding is used for DC motors, while wave winding is used for AC motors.

• Lap winding connects the armature coils in parallel, while wave winding connects the armature coils in series.

What is the purpose of lap winding construction?

• To increase the voltage generated in the armature winding of a DC machine.

• To make the machine more energy efficient.

• To improve the cooling system of the machine.

• To reduce the voltage generated in the armature winding of a DC machine.

How is wave winding construction different from lap winding construction?

• Wave winding has no paths for current flow.

• Lap winding has only one path for current flow.

• Wave winding has only two paths for current flow.

• Wave winding has three paths for current flow.
