(2)    根据该实验请你判断下列k-△h图象中正确的是

    

 

(II)、应用《伏安法测电阻》时,由于电压表、电流表内阻的影响,使得测量结果存在着误差,而按图中所示的电路进行测量,则可以避免由电压表和电流表内阻所带来的误差。电流表和电压表的量程分别用0~ 0.6A和0~ 3V档。  

①  请在下列横线上简要写出还未完成的主要操作步骤,并用字母表达相应测量值

a.闭合开关S1、S2接2,调节R´p,使电压表和电流表的读数尽可能大,读出电流表和电压表读数I2、U2 b.保持Rp不变_________________________________________________________

②  请推导出待测电阻Rx的表达式           ③  用线把实物图按电路图连成测量电路,请将图中未连的线完成
