Answer / sindhu

all generators produce ac current as output.....but incase
of dc we use commutator to convert it in dc current

Answer / fireprs

All the Generators produce ac currents(in accordance with
Faraday's Law).
In DC generator the generated ac voltage is converted into
DC through commutator,while in ac gen. ac voltage is
supplied.

Answer / divya

the main difference is in dc we use split rings for
commutation which provide a phase shift of 180deg and in ac
we usr slipring.thus it all depends on the type of
commutator used

Answer / zalan

in ac generator slip rings are used which slides over
carbon brushes while in dc split rings are used and hence
dierct current flows,,now its my class time.bye

Answer / rahul

alternators are called ac generators,they are synchronous generators that runs at synchronous speed, ac&dc generators works on same principle of electromagnetic induction.in case of dc generator armature rotates and field remains stationary, where as in alternator field rotates and armature winding(stator winding) remains stationary. in case of alternator the generated voltage are taken out from the stator winding where as in dc generator the induced ac voltage is first converted to dc by using a commutator and the output is taken from the rotating commutator by using brushes. in case of alternator better insulation can provided if generated voltage are taken from stationary winding and the dc supply to field winding is provided by using brushes.

Answer / jamal mahsood

THE MAIN DIFFERENCE BETWEEN THE AC GENERATOR AND DC GENERATOR IS...IN AC GENERATOR WE USE SLIP RINGS AND IN DC GENERATOR WE USE SPLIT RINGS...

Answer / nandhini

in dc generator,rotor consists of armature conductor and stator consists of field windings.in ac generator,rotor consists of field magnet and stator consists of armature conductor. in dc generator commutator is used to convert it to dc but in ac generator no commutator is used. ac generators are also called as alternators. in dc generators split rings are used for phase displacement .in ac generators slip rings are used.

AC SLIP RINGS ARE REPLACED BY SPLIT RING CALLED COMMUNTATOR
IN DC

Answer / abdul wahab

we get output from stator and also from rotor in a.c case but in d.c case output comes from rotor not from stator side
