Alternating current cannot be measured by D.C. ammeter because

Alternating current cannot be measured by D.C. ammeter because

Options

  1. AA.C. cannot pass through D.C. ammeter
  2. BA.C. changes direction
  3. Caverage value of current for complete cycle is zero
  4. 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.
