An ammeter has a non-negligyybxu .n5.h,p:-kv3 8w5ivk bx etoa: ib a o*bcz7dv3/qyjni: 5le zero offset error. Which of the following statements is cor5 bnv*cyij7oz/: q a3drect?
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 erro1hlljc bd 6+ j5kzzm9 *opfa+l7zow 08r 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 reproducible the measurements are when the experiment is repeated. Precision is unaffected by a sz905jw 1hpbjk *+lzo of+aldml87 z6cystematic error.
