An ammeter has a non-negligible zero offsed uh (8q:v0 lp,6qmmclb07eset error. Which of the following statedl*hi/ ypk y5k/; y8smments is coy5h/8kd;i/*k ly spym rrect?
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 inh ny-h o1)-t.xxdxzf. 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 how reproducible the measurements are when the experiment is repeatedx-t.)-o.1 hxdznfxy h. Precision is unaffected by a systematic error.
