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.

参考答案:  D


本题详细解析:
The zero offset error wit:9 g.qxv3ax oll 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 .:gqtaox9 vx3 when the experiment is repeated. Precision is unaffected by a systematic error.
