某校课外物理兴趣小组利用图所示进行了一次物理实验探究活动 某校课外物理兴趣小组利用图所示电路进行了一次物理实验 探究活动 某校课外物 理兴趣小组利用图所示电路进行了一次物理实验探究活动( 此实验中使用了如下器 材:6V 蓄电池组一个;学生用电流和电压表各一个;5Ω 定值电阻一个;0,10Ω 滑动变阻器一个;开关一个;导线若干( (1)探究步骤: ?先使滑片在滑动变阻 器最右端，闭合开关，读出并此时电压表示数 V1 和电流表示数 I1; ?调节 滑片的位置，使它移动到滑动变阻器中点(假设可精确调节)，读出并记录此时电 压表示数 V2; ?调节滑片的位置，使它移动到滑动变阻器最左端，读出并记录此 时电压表示数 V3 和电流表示数 I3(请你根据所学知识和以上的探究步骤，填出 该小组读出的电压表的三次示数( (2)滑片在滑动变阻器最右端时的电流表示数 I1 和滑片在滑动变阻器最左端时电流表示数 I3 的比值是 1:3 1:3 ( (3)该小组 进行的实验是探究在串联电路中电阻 电阻 一定的情况下，电压与电阻之间 电压与 电阻之间 关系(在实验成功的基础上，探究出的结论应该是:串联电路中导体两端 的电压与导体的电阻成正比 串联电路中导体两端的电压与导体的电阻成正比 (考 点:串联电路的电压规律(专:简答题;压轴题(:解决本题要根据滑动变 阻器的位置确定连入电路的总电阻，结合串联电路的电流相等，电压与电阻成正比 的特点进行分析(解答:解:(1)当滑片在滑动变阻器最右端时，根据欧姆定律公 式 I ， I1 0.4A， U1I1R0.4×52V; (2)当滑片在滑动变阻器中间时，根据欧姆 定律公式 I ， I1 0.6A， U1I1R0.6×53V; (3)当滑片在滑动变阻器最右端时， I1 1.2A， U1I1R1.2×56V; 故答案为:(1)表格数据如根据欧姆定律公式 I ， 下: (2)1:3 (3)电阻，电压与电阻之间，串联电路中导体两端的电压与导体 的电阻成正比(点评:串联电路中的电流处处相等，根据公式 UIR 可知，各电阻 分担的电压与电阻成正比(bUt2LkCbUt2LkCb Ut2LkCbUt3MlDcVu3MlDc Vu3MlDcVu3M lDcVu3NmEdWv4NmEdWv4N mEdWv4NmEd Wv4NmFeXw5OnFeXw5OnFe Xw5OnFeXw5O nFfYx6PoGfYx6PoGfYx6P oGfYx6PoGf Zy7Qp-HgZy7Qp-HgZy7Qp-Hg Zy7Qp-HgZy8R qIhz8RqIhz8RqIhz8R qIhz8Sr0Ji A9Sr0JiA9Sr0JiA9Sr0Ji A9Sr1KjBaT s1KjBaTs1KjBaTs1KjBaT s1KkCbUt2Lk CbUt2LkCbUt2LkCbUt2Lk DcVu3MlDcV u3MlDcVu3MlDcVu3MlDdW v4NmE W dWv4Nm EdWv4NmEd v4NmEdWw5On FeXw5OnFeX w5OnFeXw5O FeXw6PoGfY x6Po n Y GfYx6Po GfYx6PoGf x6Pp-HgZy7Qp -HgZy7Qp-HgZ y7Qp-H gZy7Qp-Ihz8RqIh z8RqIhz8R qIhz8RqIi A9Sr0JiA9S r0JiA9Sr0Ji A9Sr0JiBaT s1KjBaTs1Kj BaTs1KjBaT s1KjBaUt2Lk CbUt2LkCbU t2LkCbUt2Lk CbUu3MlDcVu3MlDcVu3Ml DcVu3MlDcV u3NmEdWv4NmEdWv4NmEdW v4NmEdWv4Nm FeXw5OnFeXw5OnFeXw5On FeXw5OnGfY x6PoGfYx6PoGfYx6PoGfY x6PoGf Zy7Qp -HgZy7Qp-HgZy7Qp-HgZy7Qp -HgZy8RqIh z8RqIhz8Rq Ihz8RqIh z8Sr0JiA9Sr 0JiA9Sr0Ji A9Sr0JiA9Sr 1KjBaTs1Kj BaTs1KjBaTs1KjBaTs1Lk CbUt2LkCbUt 2LkCbUt2LkCbUt2LkDcVu 3MlDc Vu3Ml DcVu3MlDcVu3MlDdWv4Nm EdWv4NmEdWv4NmEdWv4Nm EdXw5OnFeX w5OnFeXw5On FeXw5OnFeX w6PoGfYx6Po GfYx6PoGfY x6PoGfYx6Pp -HgZy7Qp-HgZ y7Qp-HgZy7Qp -HgZy7QpIh z8RqIhz8Rq Ihz8RqIh z8RqIiA9Sr 0JiA9Sr0Ji A9Sr0JiA9Sr 0JiBaTs1Kj BaTs1KjBaTs 1KjBaTs1Kj BbUt2LkCbUt 2LkCbUt2Lk CbUt2LkCbUu 3MlDcVu3Ml DcVu3MlDcVu 3MlDcVu3Nm EdWv4NmEdWv 4NmEdWv4Nm EdWv4NnFeXw 5OnFeXw5On FeXw5OnFeXw 5OnGfYx6Po GfYx6PoGfYx 6PoGfYx6Po GfZy7Qp-HgZy 7Qp-HgZy7Qp- HgZy7Qp-HgZz 8RqIhz8Rq Ihz8RqIhz 8RqIhz8Sr0 JiA9Sr0JiA 9Sr0JiA9Sr0 JiA9S r1KjBaTs1KjBaTs 1KjBaTs1Kj BaTs1LkCbUt 2LkCbUt2Lk CbUt2LkCbUt 2LkDcVu3Ml DcVu3MlDcVu 3MlDcVu3Ml EdWv4NmEdWv 4NmEdWv4Nm EdWv4NmEdXw 5OnFeXw5On FeXw5OnFeXw 5OnFeXw6Po GfYx6PoGfYx 6PoGfYx6Po GfYx6Qp-HgZy 7Qp-HgZy7Qp- HgZy7Qp-HgZy7QpIhz8RqI hz8RqIhz8RqIhz8RqI iA9Sr0JiA9 Sr0JiA9Sr0JiA9Sr0JiBa Ts1KjBaTs1K jBaTs1KjBaTs1KjBbUt2L kCbUt2LkCb Ut2LkCbUt2LkCbUu3MlDc Vu3MlDcVu3M lDcVu3MlDcVu4NmEdWv4N mEdWv4NmEd Wv4NmEdWv4NnFeXw5OnFe Xw5OnFeXw5O nFeXw5OnGfYx6PoGfYx6P oGfYx6PoGf Yx6PoGgZy7Qp-HgZy7Qp-Hg Zy7Qp h -HgZy7Q p-HgZz8RqI z8RqIhz8R qIh S z8RqIh z8Sr0JiA9 r0JiA9Sr0Ji A9Sr j 0JiA9S s1KjBaTs1K BaTs1KjBaT s1Kj U BaTs1Lk CbUt2LkCb t2LkCbUt2Lk CbUt2LkDcV u3MlDcVu3M DfYx6PoGgZ y7Qp- l HgZy7Qp -HgZy7 Qp-HgZy7Qp-HgZz8R qIhz8RqIh 8RqIhz8RqIhz9Sr0Ji A9Sr0 JiA9S r0JiA9Sr0JiA9Ss1KjBaT s1KjB aTs1Kj z BaTs1KjBaTs1LkCbUt2Lk CbUt2 LkCbU t2LkCbUt2LlDcVu3MlDcV u3MlDcVu3Ml DcVu3MlEdWv4NmEdWv4Nm EdWv4NmEdW v4NmEeXw5OnFeXw5OnFeX w5OnFeXw5On FeXx6PoGfY x6PoGfYx6Po GfYx6PoGfY x6Qp-HgZy7Qp-HgZy7Qp-HgZ y7Qp-HgZy7Qq Ihz8RqIhz8RqIhz8Rq Ihz8 RqJi A9Sr0JiA9Sr0JiA9Sr0Ji A9Sr0J iBaTs 1KjBaTs1KjBaTs1KjBaTs 1KjCbUt2Lk CbUt2LkCbUt2LkCbUt2Lk CbVu3M lDcVu 3MlDcVu3MlDcVu3MlDcVu 4NmEdWv4NmEdWv4NmEdW v4NmEdWv4On FeXw5OnFeX w5OnFeXw5On FeXw5OnGfY x6PoGfYx6Po GfYx6PoGfY x6PoGgZy7Qp -HgZy7Qp-Hg BaTs1KjCbUt 2LkCbUt2Lk CbUt2LkCbUt 2LkCbVu3Ml DcVu3MlDcVu 3MlDcVu3Ml DcVv4NmEdWv 4NmEdWv4Nm EdWv4NmEdWv 4OnFeXw5On FeXw5OnFeXw 5OnFeXw5On GfYx6PoGfYx 6PoGfYx6Po GfYx6PoHgZy 7Qp-HgZy7Qp- HgZy7Qp-HgZy 7Qp-Hgz8Rq Ihz8RqIhz 8RqIhz8Rq Ihz9Sr0JiA 9Sr0JiA9Sr0 JiA9Sr0JiA 9Ts1KjBaTs1 KjBaTs1KjB aTs1KjBaTs2 LkCbUt2LkC bUt2LkCbUt2 LkCbUt2LlD cVu3MlDcVu3 MlDcVu3MlD cVu3Ml EdWv4NmEdWv4Nm EdWv4NmEdWv 4NmEeXw5On FeXw5OnFeXw 5OnFeXw5On FeYx6PoGfYx 6PoGfYx6Po GfYx6PoGfYx 7Qp-HgZy7Qp- HgZy7Qp-HgZy 7Qp-HgZy7QqIhz8RqI hz8RqIhz8RqIhz8Rq0J iA9Sr0MlDc Vu3MlDcVu3MlEdWv4NmEd Wv4NmEdWv4N mEdWv4NmFeXw5OnFeXw5O nFeXw5OnFe Xw5OnFeYx6PoGfYx6PoGf Yx6PoGfYx6P oGfYx7Qp-HgZy7Qp-HgZy7Q p-HgZ R y7Qp-Hg Zy7RqIhz8 qIhz8RqIh z8RqIhz8R q0JiA9Sr0J A9Sr0JiA9S r0Ji i T A9Sr0Jj BaTs1KjBa s1KjBaTs1Kj BaTs k 1KjCbU t2LkCbUt2L CbUt2LkCbU t2LkCcVu3Ml DcVu3MlDcVu3MlDcVu3Ml DcVv4NmEdW v4NmEdWv4NmEdWv4NmEdW v5OnFeXw5On FeXw5OnFeXw5OnFeXw5Oo GfYx6PoGfY x6PoGfYx6PoGfYx6PoHgZ y7Ts1KjBaTs 1KjBa Ts1KjCbUt2LkCbU t2LkCbUt2Lk CbUt2LkCcVu3MlDcVu3Ml DcVu3M lDcV u3MlDcWv4NmEdWv4NmEdW v4NmEd Wv4Nm EdWv5OnFeXw5OnFeXw5On FeXw5O nFeX w5OoGfYx6PoGfYx6PoGfY x6PoGfYx6Po -HgZy7Qp-HgZy7Qp-HgZy7Qp -HgZy7Qp-Hh z8RqIhz8RqIhz8RqIh z8RqIhA9Sr 0JiA9Sr0JiA9Sr0JiA9Sr 0JiAaT s1Kj BaTs1KjBaTs1KjBaTs1Kj BaTt2LkCbUt 2LkCbUt2LkCbUt2LkCbUt 2MlDcV u3Ml DcVu3MlDcVu 3MlDcVu3Mm EdWv4NmEdWv 4NmEdWv4Nm EdWv4NmFeXw 5OnFeXw5On FeXw5OqIhA9Sr0JiA9Sr0 JiA9Sr0JiA 9Sr0JiAaTs1KjBaTs1KjB aTs1KjBaTs1KjBaTt2Lk CbUt2LkCbUt 2LkCbUt2Lk CbUt3MlDcVu 3MlDcVu3Ml DcVu3MlDcVu 3MmEdWv4Nm EdWv4NmEdWv 4NmEdWv4Nm FeXw5OnFeXw 5OnFeXw5On FeXw5OnFfYx 6PoGfYx6Po GfYx6PoGfYx 6PoGfYy7Qp- HgZy7Qp-HgZy 7Qp-HgZy7Qp- HgZy8RqIhz 8RqIhz8Rq Ihz8RqIhz 8Rr0JiA9Sr0 JiA9Sr0JiA 9Sr0JiA9Sr0 KjBaTs1KjB aTs1KjBaWv4 NmFeXw5OnF eXw5OnFeXw5 OnFeXw5OnF fYx6PoGfYx6 PoGfYx6PoG fYx6PoGfZy7 Qp-HgZy7Qp-H gZy7Qp-HgZy7 Qp-HgZy8RqI hz8RqIhz8 RqIhz8RqI hz8Rr0JiA9 Sr0JiA9Sr0J iA9Sr0JiA9 Sr1KjBaTs1K jBaTs 1KjBaTs1KjBaTs1 KkCbUt2LkC bUt2LkCbUt2 LkCbUt2LkD cVu3MlDcVu3 MlDcVu3MlD cVu3MlDdWv4 NmEdWv4NmE dWv4NmEdWv4 NmEdWw5OnF eXw5OnFeXw5 OnFeXw5OnF eXw5PoGfYx6 Pr0JiA9Sr0J iA9Sr1KjBa Ts1KjBaTs1K jBaTs1KjBa Ts1KkCbUt2L k
