问答题

(1)①在用游标为10分度的游标卡尺测某金属棒的直径时,示数如图1所示,读数为______cm.

②在测定金属丝的电阻率的实验中,用螺旋测微器测量金属丝的直径,示数如图1所示,读数为______mm.

(2)用多用电表的欧姆挡测量阻值约为几十kΩ的电阻Rx,以下给出的是可能的操作步骤,其中S为选择开关,P为欧姆挡调零旋钮,把你认为正确步骤前的字母按合理的顺序填写在横线上______.

a.将两表笔短接,调节P使指针对准刻度盘上欧姆挡的零刻度,断开两表笔

b.将两表笔分别连接到被测电阻的两端,读出Rx的阻值后,断开两表笔

c.旋转S使其尖端对准欧姆挡×1k

d.旋转S使其尖端对准欧姆挡×100

e.旋转S使其尖端对准OFF挡,并拔出两表笔

(3)使用多用电表测量电阻时,多用电表内部的电路可以等效为一个直流电源(一般为电池)、一个电阻和一表头相串联,两个表笔分别位于此串联电路的两端.现需要测量多用电表内电池的电动势,给定的器材有:待测多用电表,量程为60mA的电流表,电阻箱,导线若干.实验时,将多用电表调至×1Ω挡,调好零点;电阻箱置于适当数值.完成下列填空:

①仪器连线如图2所示(a和b是多用电表的两个表笔).若两电表均正常工作,则表笔a为______(填“红”或“黑”)色;

②若适当调节电阻箱后,图1中多用电表、电流表与电阻箱的示数分别如图3(a),(b),(c)所示,则多用电表的读数为______Ω,电流表的读数为______mA,电阻箱的读数为______Ω:

③由于多用电表表头的电流刻度是均匀的,电流强度与格数成正比,利用此关系,将图l中多用电表的两表笔短接,此时流过多用电表的电流为______mA;(保留3位有效数字)

④计算得到多用电表内电池的电动势为______V.(保留3位有效数字)
