An ammeter has a non-negligijvs80l ol4u-j ble zero offset error. Whi5d tqmwi); nz7naykfu s(( 19+4pj rrpch of the following statementsw4t mu( jppndai7fk9qzrr 1s)(5 ;y+n 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 rea*gj;h)6 unc-u vr,) kpp9ox qbdings. A large systematic error results in measurements which are not accurate, in other words far from the cgkq-juxpr bp 9),uonc6h)*;v orrect value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
