坛主！限流电阻 穿在正级好还是负极好呀！？？？

kidcao1987 发表于 2009-2-12 19:45:20

来顶一下~~~~~~~~~~~~~~~~~

七彩光电 发表于 2009-2-14 14:10:54

表 生气， 我来贴一下标题栏！

七彩光电 发表于 2009-2-14 14:12:15

再贴。

限流电阻 穿在正级好还是负极好呀！？？？

限流电阻 无极性之分 只要串了就行

71008113 发表于 2009-5-13 19:31:38

好。不错。正在学习中

电子琴 发表于 2009-5-13 22:46:57

电阻是不分正负极的哈哈

gaozhigang198 发表于 2009-5-14 21:48:12

电阻接在什么地方都行

替楼主回复：限流电阻穿在正级好，穿在负极也好，理论上{:1_126:} 没啥差别

YJFLF 发表于 2009-6-19 18:14:08

LED测试盒怎么用啊？？？

wy2005 发表于 2009-6-30 10:58:39

网上看到一个测试仪，既可测灯珠漏电，又可配比电阻值。把红黑夹子夹在灯串两端，拨动开关，能显示你想配比的电阻值，老大能否做一个让大家分享。
