• 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?

• 电功电功率的题目在用电高峰时,小明和小方发现家中的灯变暗了,他们想可能是灯两端的电压变低了.为了测除灯的实际电压值,他们将家中的其他用电器都关掉,只让一盏“220V 100W”的灯工作.小明用秒表测得电能表的表盘转过n转所用的时间是t秒,算出其实际电功率（电能表表盘上标有N转/kwh的字样）.然后根据灯泡的规格,算出灯泡的电阻,最后求出两端的实际电压U1；而小方在电工的指导下用专用电表直接测出了灯两端的电压值U2.问：1.写出U1的表达式：U1= ＿ V（用已知量和直接测量量表示）2．通过分析可知；U1 ＿ U2 (填"大于""小于"或"等于"
