In Alternative current
it cover two half cycle one is positive or another is negative.
SO .when we calculate the net value of AC current we get Zerro
in dc ammeter value is same Because in DC current is always positive.
So., AC current is Alter and DC current Same. SO AC current can't be measured by DC Ammeter.
