An ammeter has a non-n-1;sj bbbv) kg25jx);+ cxflyt+s. ou 1k hnuoegligible zero offset erron muxp c7z23uz/w g.)or. Which of the following statements is corrz 7zo2. gc)m/uxuw 3pnect?
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 7; hcrxw7xiio:31p jfaq8.c wammeter 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 twf r3 ;w.7px8:axi q7hcjc o1ihe measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
