Lap winding is composed of

The correct answer is: A. Any even number of conductors.

A lap winding is a type of winding used in electrical machines. It is composed of a series of conductors that are connected in parallel. The number of conductors in a lap winding must be an even number, so that the ends of the conductors can be connected to the commutator.

A lap winding is more efficient than a wave winding, because it has less copper loss. However, it is more difficult to manufacture, because the conductors must be individually insulated.

Here is a brief explanation of each option:

• Option A: Any even number of conductors. This is the correct answer, as explained above.
• Option B: Any odd number of conductors. This is incorrect, as the number of conductors in a lap winding must be an even number.
• Option C: That even number which is exact multiple of poles + 2. This is incorrect, as the number of conductors in a lap winding does not need to be a multiple of the number of poles.
• Option D: That even number which is exact multiple of poles. This is incorrect, as the number of conductors in a lap winding does not need to be a multiple of the number of poles.
