A 4-Pole D.C. Generator has a speed of 1500r.p.m. Then what
will be the frequency of D.C. Generator ?

Answer Posted / kj

The generator will put out a DC voltage with a slight
ripple. The ripple frequency will depend on the number of
coils on the armature and the number of segments on the
commutator.
It will not have a frequency similar to AC.
