An ammeter has a non4vn fek,rctrv9.e y6: jgapj4f3+3jy -negligible zero offset error. Whicafrr; bbs.cag*8/zjc+z,rwy rqc +9 3h of the following statemgfrs+;zwqc*r cc/8a ra,r ybj9.b3 +zents 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 th( 2tu/es 4ogi e,/pbxrks ,a j3x:qib+e ammeter readings. A large systematic erroi4b, i/begk q ss:ju(r x/tpo +2xea,3r results in 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.
