[单选题]
An ammeter has a non-negligible zero offs0n ane rsqot;-ec0 :c /1v+r8q,gtreset error. Which of the following staljv6wi 775c..omhd94cx ot*lyrv v-ftementf4x 657iro*wcv.cl9 hj 7.mdtvv-lyos 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 :f.xk4fu hnx/will 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 the experiment is repeated. Precision is unaffected by a syst xu.:h /4kfnxfematic error.
