An ammeter has a non-negligible zero offse,-r : y8 cb78dlemntcgt ers154rbjbi 9m: k yxzm(09o uzzror. Which of the following statemen9zmbz:ork1u 0i jb9(4smyxz5 ts 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 systemaf cfzx7cxa5f97ou67 d tic 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 reproducible the measurements are when thexc zc7of7x6u75 fad9f experiment is repeated. Precision is unaffected by a systematic error.
