A) AC cannot pass through DC ammeter
B) AC changes direction.
C) average value of current for complete ycle is zero
D) DC ammeter will get damaged
Correct Answer: C
Solution :
The full cycle of alternating current consists of two half cycles. For one half, current is positive and for second half, current is negative. Therefore, for an AC cycle, the net value of current average out to zero. While the DC ammeter, reads the average value. Hence, the alternating current cannot be measured by DC ammeter.
