An ammeter has a non-neglil . a:w;j6j0 s;dmzstqgible zero o*wpsd1n(n+x 7 xu 89emyoiqb,ffset error. Which of the following statements is corrun 1x ym n*ep7,dxqbi9s(+wo8ect?
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 errorf 5kw2kv-k;sve4sbe5 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 reproducible the m4;kbvfk-5 ek w5se v2seasurements are when the experiment is repeated. Precision is unaffected by a systematic error.
