• 电容直接接在电源两端 t=0+时,电压是多少?书上说电容两端电压不能突变,那连接的瞬间,是否电路相当于短路,所以U0=0,但短路会电流,电源有内阻,是否电流等于E/R ,那么这个电流会通过电容吗?（电容是两块板,中间是介质,就是说是否有电子流过介质,如果没有,那这不是相当于开路吗?又怎么会有电流）就像我们拿一节电池,两端接导线和块板,难道就有电流了?

• 现有一个可以显示通过自身电流的电阻器Rg，其允许通过的最大电流为1mA，阻值约为几百欧．另外还提供以下器材：量程为0～10V的电压表、阻值为7500Ω的定值电阻R0、电压可调的电源、开关各一只，导线若干．为了测出这一电阻器Rg的阻值，甲、乙两同学分别设计了如下两个电路：（1）你认为应选用______电路（选填“甲”或“乙”）；（2）选用了正确的电路后，得到下表中的四组数据，请根据表中数据在坐标纸上作出U-I图象；（3）根据图象可求得Rg的阻值为______Ω．实验序数电压表示数U/VRg显示电流I/mA12.00.2524.00.5036.00.7648.00.99
• 几道电功率,1.一标有2.5V 0.3A字样的灯泡L和最大电阻为20欧的滑动变阻器R串联,接到电压为U的电源上,下列错误的是A.若U=2.5V,无论怎么样移动滑片P,电路的总功率均不会超过0.75WB.若U＞2.5V,且不损坏灯泡和变阻器,无论怎么样移动滑片P,电路的总功率一定大于0.75WC.当滑片P移动至某个位置时,L和R的电功率可以相等D.若U＜2.5V,无论怎么样移动滑片P,L均不能正常发亮.2.一电动机线圈的电阻为1欧姆,线圈两端所加的电压为2V时,电流为0.8A,电动机正常工作.(1）在求电动机正常工作1分钟所消耗的电能时,有以下两种不同的解法小明解：W=UIt=2V×0.8A×60s=96J小华解：W=I²Rt=（0.8A）²×1Ω×60s=38.4J你认为哪位同学对,做出判断并说明理由（2）求电动机正常工作1分钟所转化的机械能同学，好歹我打了那么多，你的回答真简略
