An ammeter has a non-negligible /l or) o.w-h(semibgp 7x :;cczero offset error. Which of the follod,x66 9. wban 9mr0,0zw vj60uvaqegr8 rfcnb wing statements i6,, 0bvjag. 6wrwn bra0cexr0qnud6 fmv899zs 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 aar8rr*vcz kp(* e 4+ny systematic error in the ammeter readings. A large systematic error results in measurements whichz8r r*v(kae *nyc+ p4r 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 systematic error.
