There is no difference in principle, for volts can only be generated from motion when magnetic field changes. Thus we use AC when we want the volts, curent and magnetic field to keep changing. We use DC when we want it steady or at least constant-direction - as in electroplating.

Simple battery cell produces positive one end and the other negative. DC generator just like simple battery cell. In AC generator the polarity changes where in some countries it is 50 times per seconds, unit Hertz, 50Hz Transmitting AC voltages for long distance is cheaper than DC voltages since transformer can easily stepped up the voltage to reduce the voltage drop. Edison(DC) versus Nikola Tesla(AC). Tesla won and the whole world is using AC system to power up all the country.

This is definitely not an injective statement
Also, why are we talking about this so many months later? MRWhy hasn't been back since writing here, and ... well, let's just say that these users barely come around anymore!
