Ac current can be transmitted over long distances wheares dc can be transmitted over short distance
Ac current is used in high power devices whereas direct current is used in electic chargers and low power devices
Dc =A current that flows in one direction only is called direct current Ac=A current that reserves it\’s direction periodically called alternating current
The frequency of ac current in india is 220v whereas dc current has o frequency
read the book for a whilethen you\’ll get the answer
The current which changes it\’s direction periodically is called alternating current and current which always flows in one direction is called direct current
