An ammeter has a non-negligible zero offset err6bp z w-v/*d/a,f zztkor. Which of the folld6 b((9z -ewdtrf wi3 ;yo9wkeowing statements6ybtkwwd(i ;e(-z rd9foe 93w 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 readi h5-/p9 3mqovq0 r6fd:vdjv mwngs. A large systematic error results in measurements which are not accurate, in other words far from the 6jq3rpd 5d/ mvfmw- vq09:oh vcorrect value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
