An ammeter with a full-scale range of 0-6 amperes would not be able to measure accurately a current flow of 0.2 amperes. The answer to this problem is to ____.
A) wrap just one turn of wire around the jaw of the ammeter to change the secondary-scale value
B) simply change the secondary-scale value setting
C) wrap multiple turns of wire around the jaw of the ammeter to change the secondary-scale value
D) none of the above

Wrapping multiple turns of wire around the jaw of the ammeter will change the secondary-scale value and allow for an accurate measurement of a lower current flow. This is because the current is multiplied by the number of turns, effectively creating a higher current reading on the secondary scale. Wrapping just one turn of wire would not provide enough of a change to accurately measure the lower current, and simply changing the secondary-scale value setting would not account for the limitation of the physical meter itself.
