An ammeter has a non-negligible zeadr0a8f2 gvb nl2+ c+f4(zatirog m 9jc((ybgv4 offset error. Which of the following statements is corm9gj4c (vb y(grect?
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 systemati yt1;+ xyqk9ncc error in the ammeter readings. A large systematic error results in mt 9yxnyc1;+kq easurements which are not accurate, in other words far from the correct value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
