1,finally,the thief handed everything______he had stolen to

1,finally,the thief handed everything______he had stolen to the police.(Q:为什么填that 而不是which?)
2:如图所示的电路中,电源电压为4.5V不变,电阻R1标有“6Ω 0.5A,”滑动变阻器R2标有30Ω1A,电流表量程是“0~0.6安”.电压表量程为“0~3V”为了保护个电表和元件,滑动变阻器R2允许接入电路的阻值范围是——

1.不定代词后面只能用THAT
2.先求出电路最大承受阻值为 4.5V除以0.6A=7.5欧
1.由这个得到的滑动电阻阻值最小为7.5-6=1.5欧
2.电压表最大为3V ,即R2：R1最大比为 2“1,那么R2最大为 12欧
3.在根据 R1最大接受电流为0.5A 可知电路的电流不能大于0.5A,所以总阻值4.5/除以0.5=9欧 9-6=3欧,及说明这个条件下的R2阻值应该不小于 3欧
综上所述 R2 范围为 3-12欧
