An ammeter has a non-negligible zero7 m b/g1wnirmm1n y8/ k+dr3xg- 4o jemr8yn;9smyfse jb0f4 0 offset error. Which of the following statements is-n08m fsbes4me 49;j0jory f y 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 reading/g8fb kn(;:zq*qgk v+ xcxvx.s. A large systematic error results k8qgk ng/x*:vcx vfb.+q z;(xin measurements 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.
