Answer / jyothi

In DC Generators AC voltage induces in armature winding &
AC is converted to dc with the help of commutator.

In AC Generators supply is taken from armature through slip

Answer / vaijanath nirgude

in ac generator the dc excitation is given to the rotor
for producing rotating electromagnetic field & emf induced
in the stator is ac.
in dc generator magnetic field is produced by permanent
magnet or by electro magnet & emf is induced in the
armature is ac & it is converted to DC by using commutator
