explain why the armature voltage changes when the field rheostat is varied in self excited DC gene..

Answer / sandip koley

The formula of induced emf E=flux*Z*N/60*(P/A)
if field rheostat is change the field current will
change.this change in field current change the flux.as the
flux change the EMF also change as E is directly
Proportional to field flux.



here Z=no of conductor
N=RPM
P=no of pole
A=no of parallel path.
