Correct Answer - Option 3 : 2

**Concept:**

Armature emf in a DC generator is given by,

\({E_g} = \frac{{\phi ZNP}}{{60A}}\)

ϕ is flux per pole

Z is the number of conductors

N is speed

P is poles

A is the number of parallel paths

For the lap winding, A = P

For the wave winding, A = 2

**Calculation:**

To have the same emf, the number of parallel paths must be same in both the cases.

Therefore, the number of parallel paths = A = P = 2

Number of poles = 2
