An ammeter has a non-negligible zero offset err4 eq-5yoq o;ddor. Which of the following statemd5qe oq;-o 4ydt16itv, cm*,le nf7 knk7lv6n1e,nmi fc ,tt *ents is correct?
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 wilu/wz0 tf1 d,nyl produce a systematic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. Precision refers to howd z0 ,1wfun/yt reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
