An ammeter has a non-negligible zq *.we2jts/7,dsl:yan vv y1pero osi.4e0s91 vtfn t-benrlrk+ 2ffset error. Which of the following statements is cbsftr42e9 vi n+-k1l0r .ts neorrect?
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-ripbdnk 2 3(n qaze*qvw3e7 vu y7;w/ will produce a systematic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. Precision refers to how reproduc */7nir wzad7k(pu2 qyv;bne -weq3v3ible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
