Question

what is differanc between ac and dc generator​

Answer 1

The major difference between an AC Generatorand a DC Generator is that the DC Generatorrequires a mechanism to provide a DC output. This can be done mechanicallywith a commutator or electronically with arectifier. Internally,

allgenerators produce an alternating voltage. ... Allgenerators require a magnetic field.

OR

D.C. generator: To get a direct current, a split-ring type commutator must be used. The generator is thus called a D.C generator. The only difference between a D.C generator and an A.C generator is that the two ends of the generator coil are linked to the outer circuit. ... There is no commutator in an A.C. generator.
