emf = P * φ * Z * N / A * 60 Where,
φ = Flux per pole in Weber.
Z = Total number of armature conductors.
P = Number of poles.
A = Number of parallel paths in armature.
N = Speed in rpm.
emf = emf generated in one parallel path and it is the emf generated of that generator.
For a wave wound generator there are only two (2) parallel paths in the armature. In such cases A=2 and in lap wave wound armature parallel paths is equal to the number of poles in the armature winding.
