An ammeter has a non-negligible zero offset mh4 qptabt,- qx4s:1d v1u8r verror. Whichq;mq2qo urs+ xcn(* u2d 18 hjvsym;j+ of the following statements;qmu81cjqs m+*nv;x dj2(+ qu 2sohyr 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 ammhaq ) i;y,u8ty7x 1cvaeter readings. A large systematic error r;,u71ahycxvqit y8a )esults 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 systematic error.
