那成本要多少你不讲，不讲成本都是在耍流氓。而且这种结构你不能在通用插座面板上设计数个插孔，如果采用我国现在的那种插座标准，这个有孔插头有时会被国标插座的铜片钩住而无法拔出，这个我是以前用有孔插头时是有体会的。

你很善良，厂商想说的话都让你代言了。国内一个插排动辄几十上百元，220v规制本来用铜量就比日本的110v少，怎么反而中国的成本更高了？日本市场上卖的插排一般都在1000日元均价，合人民币50多，日本人工比中国贵得多，难道日本厂商都做亏本生意？

线阻应该和实物电阻是并联关系吧。你测量实物电阻的电压的时候，万用表的电阻是无穷大，（线阻+无穷大之和）与实物电阻并联。你在求电流时无需减去线阻。

不是因為電解液重量 是因為電池是像一條長彩帶捲起來 電子儲存在彩帶負極材料上 彩帶越長就越厚也越重 但越長內組也增加 所以C數通常18650>21700>26650>32650 32幾乎已經剩1C 更長捲起來的4860電流輸出會很弱所以特別做成全極耳降低內阻
