An ammeter has a non-negligible zero offset error. Wm ih;u 7mhdhbtn0qv3 8 v+w29vhich of tk*a1m/0hhqs d u1n2b vhe following statemen1ubs2qn akdv * /mhh10ts 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 systematic error in the ammetebe 22 csun88fur readings. A large systematic error results in measurements which are not accurate, inesu82bfn uc8 2 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 systematic error.
