An ammeter has a non-neglijdhwu:scl1(a)c+ /gko4d23v :whkun t + qcy.9hf9ykgible zero offset error. Which of the following statements 9vf:th 4knyy . q+3wuo92kcd his 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 ap)c 2 k1hozwp ,++kugi systematic error in the ammeter readings. A large systematic error results in measurements which are not accurate, in other words far fr12kgpuo+h+wc ip, zk )om the correct value. Precision refers to how reproducible the measurements are when the experiment is repeated. Precision is unaffected by a systematic error.
