An ammeter has a non-negligible(.ovfa :0ofgedu .k( c ,r :f5ge0/w8 r;+hutaq; 8vmqhgswgu zero offset error. Which of the following statementsgwg/85hqgha0+s rvfuwe, : mu ;;tr8q 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 proj0yy y-ghd- :yfacr/ z m/nl:.duce a systematic error in the ammeter readings. A large systematic error results in mea hmny jrf dy/0a:-gy.yl-/c :zsurements 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.
