Ⅰ.为了测量某一弹簧的劲度系数,降该弹簧竖直悬挂起来,在自由端挂上不同质量的砝码。实验册除了砝码的质量m与弹簧长度l的相应数据,七对应点已在图上标出。(g=9.8m/s2)

(1)作出m-l的关系图线;

(2)弹簧的劲度系数为    N/m.

Ⅱ.(1)某同学实用多用电表粗略测量一定值电阻的阻值,先把选择开关旋到“×1k”挡位,测量时针偏转如图(a)所示。请你简述接下来的测量过程:

                                

                                

                                

④测量结束后,将选择开关旋到“OFF”挡。

(2)接下来采用“伏安法”较准确地测量该电阻的阻值,所用实验器材如图(b)所示。

其中电压表内阻约为5k ,电流表内阻约为5 。图中部分电路已经连接好,请完成实验电路的连接。

(3)图(c)是一个多量程多用电表的简化电路图,测量电流、电压和电阻各有两个量程。当转换开关S旋到位置3时,可用来测量        ;当S旋到位置       时,可用来测量电流,其中S旋到位置       时量程较大。
