Difference Between AC and DC Generator
AC generators produce a high voltage which varies in amplitude and time. The output frequency varies (mostly 50Hz to 60Hz). DC generators produce a low voltage when compared to AC generator which is constant in amplitude and time i.e. output frequency is zero. 11: Maintenance. AC generators require very little maintenance and are highly reliable.
