An ammeter has a non-negl81+bxt5phf f rigible zero offset errormn: ag*ey 7eoil 605nx. Which of the following statements is ce n57xylo0:6ai mg* enorrect?
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 will0ai m3 elk:ids1wi4-i 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 how reproducible the measurements are when :e -m4k31idwa i i0islthe experiment is repeated. Precision is unaffected by a systematic error.
