What is the formula of the magnetic to electrical boarding ratio?

A. magnetic to electrical boarding ratio = number of poles * permeance coefficient * flux per pole/number of conductors * armature current
B. magnetic to electrical boarding ratio = number of poles / permeance coefficient * flux per pole*number of conductors * armature current
C. magnetic to electrical boarding ratio = number of poles + permeance coefficient * flux per pole/number of conductors * armature current
D. magnetic to electrical boarding ratio = number of poles * permeance coefficient / flux per pole*number of conductors * armature current
Answer» B. magnetic to electrical boarding ratio = number of poles / permeance coefficient * flux per pole*number of conductors * armature current
