Alternating CurrentEasy
Question
Alternating current can not be measured by D.C. ammeter because
Options
A.A.C. cannot pass through D.C.
B.A.C. changes direction
C.average value of current for complete cycle is zero
D.D.C. ammeter will get damaged.
Solution
DC ammeters are designed on basis moving coil galvanometer which calibrated with average Passed current but in AC current average is ZERO
