A rotating loop within a fixed magnetic field naturally produces an alternating voltage. Slip rings and brushes are used to connect that rotating coil to a fixed external circuit and, so, provide an alternating voltage to that external circuit.
To provide a direct voltage, a split-ring commutator and brushes are required, which is a rotating switch which reverses the polarity of the coil's output every half cycle.

Is it possible to increase speed of AC Slip Ring Induction Motor?
k;kl;kl;
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 )
What is the purpose of using slip rings?
This is the standard answer for both split ring commutator and slip ring. A split ring commutator is to reverse the current direction through an armature every half turn A slip ring is to ensure that the current continue to flow to the external circuit Last bit of additional information. Carbon brush ensure that the slip ring are in contact with the circuit containing the external load *Note: Do not get confused with split ring commutator(d.c.generator) & slip ring(a.c. generator)
Does a ac generator have a brush?
AC generators (alternators) usually have a dc supply to the rotor coils, supplied through slip-rings with carbon brushes. Because the slip-rings can be made very smooth the life of the brushes is greatly extended when compared with brushes on the commutator of a dc motor or an ac commutator motor. Cars generate electrical power with a three-phase AC alternator, connected directly to the battery through rectifier diodes. The alternator voltage is controlled by the voltage regulator, which works by controlling the dc supply to the rotor.
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.
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.
How do you change an ac motor to a DC motor?
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
What are the different types of AC motor?
slip ring, synchronous, and squirrel cage induction motors....

What is the basic difference between carbon brush of AC slip ring motor and carbon brush of Direct current commutator motor?
The only difference between slip rings and commutator is that commutator can change the frequency where as the slip rings can not do it.
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 )
What are two types of electrical currents?
The two types of electric current are AC and DC currents.

Can an ac motor generate electricity?
An ac motor cannot generate electricity but its shaft can be coupled to that of certain devices like an alternator to in order to generate electricity.
How are electriciy and magnetism related?
AC currents mate ;)
