Alternating current cannot be measured by D.C. ammeter because
Alternating current cannot be measured by D.C. ammeter because
Options
- AA.C. cannot pass through D.C. ammeter
- BA.C. changes direction
- Caverage value of current for complete cycle is zero
- DD.C. ammeter will get damaged
Correct answer
C. average value of current for complete cycle is zero
Step-by-step solution
Average value of A.C. for complete cycle is zero. Hence A.C. can not be measured by D.C. ammeter.
