An ammeter has a non-negligible zero offset error. Whioi1fg 10t -qgfa t43a /xw2fccch of the dgdh3o,t4 u mq7mf6i2 following statements is corf,6mimdgdu3 t 7 q2ho4rect?
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 systematf )ilk*1m7cr xic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in other words 7 f)xk *lcrm1ifar from the correct value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
