1、1 电路的动态分析直流电流分析思路 1(多选)(2015 长沙四校联考)如图所示，图中的四个电表均为理想电表，当滑动变阻器滑片P 向右端移动时，下面说法中正确的是()A电压表 V1的读数减小，电流表 A1的读数增大 B电压表 V1的读数增大，电流表 A1的读数减小 C电压表 V2的读数减小，电流表 A2的读数增大 D电压表 V2的读数增大，电流表 A2的读数减小 2(多选)(2015 湖北省公安县模拟考试)如图所示电路中，电源内阻不能忽略，两个电压表均为理想电表。当滑动变阻器 R2的滑动触头 P 移动时，关于两个电压表 V1与 V2的示数，下列判断正确的是()AP 向 a 移动，V1示数增

2、大、V2的示数减小 BP 向 b 移动，V1示数增大、V2的示数减小 CP 向 a 移动，V1示数改变量的绝对值小于 V2示数改变量的绝对值 DP 向 b 移动，V1示数改变量的绝对值大于 V2示数改变量的绝对值 3(多选)如图所示，电源的电动势和内阻分别为 E、r，R0r，滑动变阻器的滑片 P 由 a 向b 缓慢移动，则在此过程中(2 A电压表 V1的示数一直增大 B电压表 V2的示数先增大后减小 C电源的总功率先减小后增大 D电源的输出功率先减小后增大含电容器的电路解决含电容器的直流电路问题的一般方法(1)通过初末两个稳定的状态来了解中间不稳定的变化过程。(2)只有当电容器充、放电时，

3、电容器支路中才会有电流，当电路稳定时，电容器对电路的作用是断路。(3)电路稳定时，与电容器串联的电路中没有电流，同支路的电阻相当于导线，即电阻不起降低电压的作用，与电容器串联的电阻为等势体，电容器的电压为与之并联的电阻两端的电压。(4)在计算电容器的带电荷量变化时，如果变化前后极板带电的电性相同，那么通过所连导线的电荷量等于始末状态电容器电荷量之差；如果变化前后极板带电的电性相反，那么通过所连导线的电荷量等于始末状态电容器电荷量之和。1(多选)(2015 东北三校二模)如图所示，C16 F，C23 F，R13 ，R26 ，电源电动势 E18 V，内阻不计。下列说法正确的是()A开关 S 断开时
