There is no such thing as a Generator. All power generating devices are Alternator since both generate alternating current since this is the only way electrical power can be generated. In "generators" the alternating current is converted into DC inside the housing of the "generator" in order to give out DC Do you agree? If not please educate me. How else is DC generated if not like above?
