Difference between AC-DC |
|
Answer» \t\xa0AC 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.\tIn AC.the rotating magnets causes the change in direction of electric flow. The steady magnetism makes the DC to flow in a single direction.\tThe frequency of AC is depended upon the country. But, generally the frequency is 50Hz or 60Hz. DC has no frequency of zero frequency.\tIn AC the flow of current changes it direction backwards periodically. DC flows in single direction steadily.\tElectrons in AC keep changing its directions - backward and forward. Electrons only move in one direction that is forward in DC. Ac- alternate current Dc- direct current Batteries are dc but electricity from Transformers are ac AD |
