An ammeter has a non(mq7xef,ozy; inau m5o 1x6avkb k6 )62zz6je4 is 0:d x4ecx1k1 qu,- rqzuys-negligible zero offset error. Which of the following statements is 2yr1x6-u4,4 ez qk euc 0xjszd zsi1q: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 produce3 47dmw jc0phynsqr/w4 i r9/n a systematic error in the ammeter readings. A large systematic error results in measurementw /ismw49prn0 nhqr7j3y4/c ds 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.
