An ammeter has a non-negligible zero g9b:q gr5ul07f q2,i6hmry aa offset error. Whii* f nd-(hr70ompc.iych of the following statements is cor*cmp0y .dnfh-ir(o 7irect?
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 amme r 7r.waoe78 f zv:y5q;tjg8qdter readings. A large systematic error results in measurements which are not accurate, in other words far from the correct value. Precision refers to how reproduciw.;dtfrjg5y8v :orqa7e7q z8ble the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
