Expert Answer
In DC current the flow of electron is in single direction whereas in AC current the flow of electron switches its direction after particular time interval.AC current is safe to transfer over long distance as there is less loss of energy whereas in case od DC current lots of energy losses occured.The frequencu of AC is 50Hz on the other hand the frequency of DC current is zero.
