电压表

17. 在选择电压表的量程时,正确的是(    )

A. 尽可能选择大一些的量程      B. 选用大小不同的量程测量,测量结果同样精确

C. 经试触后被测电压不超过小量程挡,应选用小量程进行测量

D. 试触时电压表示数为2.8V,选15V的量程更好些

18. 如图9所示的电路中,电压表所用的量程不明,当电路闭合后,V和V2的示数分别如图10所示。则V用的量程是    V,V2用的量程是    V,小灯泡L1上的电压U1=            





19. 将 R1、R2两个电阻按如图11、12所示的两种方法先后连接到电压不变的电源上图11中电压表的示数是6V,电流表的示数是0.3A;图12中电压表的示数是4V,电阻R1=          Ω。
