Difference Between AC_Generator and DC_Generator:

AC Generator

The major parts of an AC generator are Armature coil, field magnet, slip rings and brushes etc. The magnet which produces magnetic flux in generator Base called field magnet. The directional flux lines is from North pole of the field magnet to South Pole and armature is a coil and which insulated in connecting wire is wound over a laminated soft iron core.

Slip rings: The slip rings are Circular Rings fused the ends of the coil. They rotate about the same axis as that of the armature. Brush: Brush is an arrangement that is always it connect was living like a current flows to the external circuit to this Armature: Armature coil rotates continuously using mechanical energy. Simultaneously, armature coil deflects the magnetic flux lines, and EMF is generated in the coil. This continuous motion of the Armature coil helps to keep a constant current in the external circuit.
Let's see the different steps in one complete rotation of the armature coil. When the Armature coil starts rotation, the angle between the axis of the coil, and direction of flex be 0 degree.
There is no EMF induced in edge because of no flux change. After that the rotation of the armature coil, cutes more flux lines and due to this, the angle between the axis of the coil and flux becomes 90°. Then maximum EMF is induced in it. When the coil jumps to 180° with the flux lines then also the emf becomes zero. When the angle jumps from 180° to 270° then the direction of the flux change become positive so that maximum EMF is produced in opposite direction. When the coil turns from 270° to 360° the rate of flux changes reduced to zero then also the e/m of becomes 0. The number of Cycles in one second is gold the frequency of AC. The unit of frequency is hertz. The frequency of AC used in our house is 50 hertz.

DC Generators: As the AC generator, the DC generator also has a field magnet and Armature coil. In dc generators the slip rings are replaced by splits rings. In DC generators are also the EMF induced by the Armature coil is Ac in nature. This EMF is converted into DC using split ring commutator. The current flows to the extensive circuit through the graphite brush is unidirectional.Let's see the difference between the emf from a DC generator and a battery. The emf from battery is of constant intensity and without any fluctuations, but the Emf from the DC source is pulsating. generator
