以家庭为例，所用的电器有感性负载也有阻性负载，因此计算额定电流是P＝UI和P＝UIcosΦ。假设家里的电器总功率为10KW，那么计算得到的最大电流I为56A。众所周知，家里的电器也不可能同时工作，因此要给予一个同时系数0.6-0.8。因此系数取0.8，计算得到45A。所以家里的总电源线可以用6平方毫米铜芯BV系列的电线电缆。实际使用过程，电线电缆的工作环境温度、电线电缆敷设方式、穿线管内穿线数等都是对电线电缆截面选择有影响的。
Eight core SYV - 75-5 coaxial cable of the radio frequency cable, home video line, etc., are SYV solid core polyethylene insulated PVC sheathed coaxial cable, 75 of which means the resistance of the conductor is 75 ohms, 5 large diameter refers to the insulation of the cable is 5 mm (4.8 + / - 0.2 mm), 5 instead of 7, 7 cannot replace with 5, because insulation in large and small, not big to small generation.

RC电路充电公式Vc=E(1-e(-t/R*C))。关于用于延时的电容用怎么样的电容比较好，不能一概而论，具体情况具体分析。实际电容附加有并联绝缘电阻，串联引线电感和引线电阻。还有更复杂的模式--引起吸附效应等等。供参考。E是一个电压源的幅度，通过一个开关的闭合，形成一个阶跃信号并通过电阻R对电容C进行充电。E也可以是一个幅度从0V低电平变化到高电平幅度的连续脉冲信号的高电平幅度。电容两端电压Vc随时间的变化规律为充电公式Vc=E(1-e(-t/R*C))。
