实验题

(10分)某实验小组探究金属丝电阻大小与长度的关系,他们取一段粗细均匀的金属丝拉直后连接在A、B接线柱上,在金属丝安装一个可滑动的金属夹P.实验室还提供了下列器材:电压表、电流表、电池组(电压3V)、滑动变阻器(20Ω 2A)、刻度尺、开关和导线若干.

(1)他们连接了如图甲所示的电路,请用笔画线代替导线,把图中还没有连接的一根导线接上,使电路完整.

(2)闭合开关前,将滑动变阻器的滑片移至变阻器的最_______ (选填“左”或“右”)端.

(3)某次实验中测得电压表的读数为2.1V,电流表指针偏转如图乙所示,则电流表的读数为I=_______A,此时金属丝的电阻R=______Ω.

(4) 实验中移动金属夹P.分别测得AP段的长度l和对应的电阻值R,数据如表:

/cm304050607080
R/Ω2.12.83.54.24.95.6
l/cm304050607080
R/Ω2.12.83.54.24.95.6
分析表中数据,可知___________________________________________________________

(5)小虎同学认为,由于电源电压没有超过电压表所选量程的最大值,因此在闭合开关前,可以将变阻器的滑片置于任意位置。你认为他的想法是        (选填“正确”或“错误”)的,理由是:                                                             

他们还想借助于图甲继续探究“电压一定时电流与电阻的关系”:

(6)闭合开关后,调节滑动变阻器的滑片,直到电压表示数为2.5V,记下电流表的示数(7)______________________________,调节滑动变阻器的滑片,使电压表示数为______V,记下电流表的示数

(8)经过多次实验,得到如图丙所示的电流I随电阻R变化的图像,由图像可得出:_________
