An ammeter has a non-negligs:wro 6 +c7+puxbc )t36k6wlqdug9 leible zero offset error. Which of the followin:58rcds wya77ysuyo 1 g statements is correct518 :s7or uysy7adcyw ?
A. The readings from the ammeter will be accurate but not precise.
B. The readings from the ammeter will be neither accurate nor precise.
C. The readings from the ammeter will be precise and accurate.
D. The readings from the ammeter will be precise but not accurate.
参考答案: D
本题详细解析:
The zero offset error will produce a systematic error in tj :qmyjc 4zu 5ep+;qo4he ammeter readings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. Precision refers to how reproducible the measuremj44zu5qy+ qj :;mcoe pents are when the experiment is repeated. Precision is unaffected by a systematic error.
