Why are slip rings used in an AC generator but not in a DC generator?

Slip rings provide a means for connecting the rotating armature of a simple a.c. generator to an external circuit. As the armature naturally produces an alternating voltage, an alternating voltages is what appears across the slip rings.
To obtain a d.c. voltage, it's necessary to reverse the direction of the natural alternating voltage every half cycle, producing full wave rectification. This is achieved using a split-ring commutator which, essentially, is a rotating switch.
So, slip rings are used with simple a.c. generators, whereas a commutator is used with d.c. generators.
Having said that, however, large modern a.c. generators (alternators) have fixed armatures, and rotating fields, and slip rings are used to supply d.c. field current to the alternator's rotating field windings.

Slip rings and split rings?
Slip rings are used in AC while split rings are used in DC generators
Purpose of slip rings?
slip ring is connect on shaft of motor to collect current from commutator without any complicate connection and with use of it resistors can be insert in circuit and therefore speed control of motor can easily achive
What is the differences between the slip and split rings?
Split rings are in AC generators ( alternating current) while slip rings are in DC current (direct current).
How can you generate a DC?
U sohuld replace the slip-ring which it is in the AC generator to a commutator. It is a split-ring. Then u can produce DC generator.
Ac generator construction?
what is the construction of ac generator
What is the function of slip rings in ac generator?
They rotate the armature coil.
In the generation of electricity commutator would be used on an alternating current generator and slip rings would be used on a direct current generator?
No. Just the opposite. An AC alternator uses slip rings, a DC generator uses a commutator. Most modern auto alternators are in fact AC alternators that rectify the AC output to DC using a diode bridge.
Slip rings and split rings?
Slip rings are used in AC while split rings are used in DC generators
What is DC generator?
because DC generator generates generally generate DC power but as it has slip rings which convert it into ac output power
When slip ring get negative charge in ac generator?
you apply dc voltage to slip rings in synchronous generators polarity will make no difference ( other than when it is first applied )
Purpose of slip rings?
slip ring is connect on shaft of motor to collect current from commutator without any complicate connection and with use of it resistors can be insert in circuit and therefore speed control of motor can easily achive
Name the essential parts of the motor and generator?
Engine Alternator Cooling and exhaust systems fuel tank voltage regulator control panel
What happens if commutator of DC generator is removed?
If the commutator is removed from your generator, you (if you connect slip rings) get AC supply instead of DC supply. the function of the commutator is to convert AC to DC supply and vice versa.Additional AnswerRemoving the commutator will also prevent you from connecting the output of the generator to its load. Remember, the generator's armature is spinning!
Is slip ring a part attached to each end of the wire loop in an ac generator?
In a very simple, laboratory-type, a.c. generator -yes. In practical generators, the output (armature) windings are part of the stator, so do not rotate and, so, don't require slip rings.
What is the differences between the slip and split rings?
Split rings are in AC generators ( alternating current) while slip rings are in DC current (direct current).
What is an alternative to carbon brushes in an ac motor?
slip rings
What is the function of a split ring commutator?
The split rings cause the direction of the magnetic field in the armature to change direction as the motor rotates. If this didn't happen the motor would not rotate. Slip rings can be used for an AC motor which causes the direction of the magnetic field to change with the AC waveform.
