Difference between A.C and D.C

1.	Difference between A.C and D.C
Answer»		\tAC can carry and safe to transfer longer distance even between two cities, and maintain the electric power.DC cannot travel for very longer distance. If does, it loses electric power.The rotating magnets causes the change in direction of electric flow.The steady magnetism makes the DC to flow in a single direction.The frequency of AC is depended upon the country. But, generally the frequency is 50Hz or 60Hz.DC has no frequency of zero frequency.In AC the flow of current changes it direction backwards periodically.It flows in single direction steadily.Electrons in AC keep changing its directions – backward and forwardElectrons only move in one direction – that is forward.\t
