A．干电池2节，每节干电池的电动势为1.5 V<img src="http://zxhx-1302712961.cos.ap-shanghai.myqcloud.com/zyk/uploadfiles/wording/6167c1360d2da861d11c950a/image34.png" width="26px" height="26px">左右，内阻较小
B．电流表A(量程为0～0.6 A，内阻约0.5 Ω)
C．滑动变阻器R1(0～10 Ω，10 A)D．滑动变阻器R2(0～100 Ω，1 A)
E．电流表G(0～3.0 mA，Rg=10 Ω)F．定值电阻R1=990 Ω
G．定值电阻R2=90 ΩH．开关S和导线若干
(1)由于两节干电池的内阻较小，现将定值电阻R0=3.0 Ω与两节干电池串联后作为一个整体进行测量。在进行实验时，滑动变阻器应选用________，定值电阻应选用________。(填写实验器材前的编号)
