In case of a 4 pole D.C. generator provided with a two layer lap winding with sixteen coils, the pole pitch will be

Solution (By Examveda Team)

Here's an explanation to help you understand the question:

First, let's define pole pitch. It is the distance between the center of two adjacent poles in a DC generator.

To calculate the pole pitch, we need to know the total number of slots or coil sides around the armature and the number of poles.

We are given:
* Number of poles (P) = 4
* Number of coils = 16
* Two layer winding means each coil has two coil sides.

Since it's a two-layer winding, the total number of coil sides is twice the number of coils: 16 coils * 2 coil sides/coil = 32 coil sides.

In a lap winding, the number of coil sides equals the number of armature conductors or slots. So, we have 32 slots.

The formula for pole pitch is:
Pole Pitch = (Total Number of Slots) / (Number of Poles)

So, Pole Pitch = 32 / 4 = 8

Therefore, the correct answer is Option B: 8.
