An ammeter has a nonap:+s- . og/xxcr(lum-negligible zero offset error. r dp -hj2;qv7t54l89uynje ih Which of the following statemn2 -v;4i7 hph9q5rjlt8yjedu 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 will produce a systematic error in the ammeter readings. 5(ihn+ 4bnteaA large systematic error results in measurements which are not accurate, in other words far from the cor 4+bn(n i5atehrect value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
