电容器并联时，相当于电极的面积加大，电容量也就加大了。并联时的总容量为各电容量之和：C并＝C1＋C2＋C3＋……顺便说说电容器的串联。若三个电容器串联后外加电压为U，则U＝U1＋U2＋U3＝Q1/C1＋Q2/C2＋Q3/C3，而电荷Q1＝Q2＝Q3＝Q，所以Q/C串＝（1/C1＋1/C2＋1/C3）Q 1/C串＝1/C1＋1/C2＋1/C3
可见，串联后总电容量减小。

电容器串联时,要并联阻值比电容器绝缘电阻小的电阻，使各电容器上的电压分配均匀，以免电压分配不均而损坏电容器。
又可知，电容的串、并联计算正好与电阻的串、并联计算相反。
电压是充电时的电压，容量与电流，电压的关系和功率相似，和负载有关，电压和容量为定量时 ，负载电阻越小，电流越大，时间越短电压和负载为定量时 ，容量越大，电流不变，时间越长
但实际放电电路中，一般负载是不变的，电容的电压是逐渐下降的，电流也就逐渐下降 。

1.电容量(uf)=电流(mA)/15 限流电阻（Ω）=310/允许浪涌电流 放电电阻（KΩ）=500/电容(uf)
2.计算方式 C=15×I C为电容容量 单位微法 i设备为工作电流 单位为安 如一个灯泡的电阻为0.6安 电容就选择 15×0.6＝9微法 在电路里串连 9微法的 电容就可以了
3.经验公式，1uF输出50mA（如果是线性的话，10000F的超级电容可以达到500兆安培的浪涌电流）
