Question

Alternating current cannot be measured by D.C. ammeter because
(a) A.C. cannot pass through D.C. ammeter
(b) average value of current for complete cycle is zero
(c) A.C. is virtual
(d) A.C. changes its direction

Answer 1

Answer:

It's "a"

Explanation:

Because Alternating cannot be measured in D.C Ammeter measures average current in AC current average current is zero for complete cycle.Hence reading will be zero

I hope it will help u
