An ammeter has a non-negligijs7 cm*:nsis p:i- gu-ble zero offset error. Which of the f5fkiius /gsjm +pm0q7g :* ib)ollowing statemi7bi:)0qf/mm gsk i g sjup5+*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 7yll y(t g3e,eammeter readings. A large systematic error results in measuremeel3e,gtly 7y( nts 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.
