简介
电容器 作为电子元件几乎存在于每一个包含电路板的设备中。大型电容器所储存的电荷足以对人身造成伤害,因此必须对其进行正确放电。
本指南将向你展示如何制作一个简单的基于电阻的电容器放电工具。
你所需要的

要制造电容器放电工具,首先要收集必备的材料。这些材料包括:
-
两根电线。对电源、电机启动电路和相机闪光灯电路中使用的大型电解电容器,电线的最小要求为线径12AWG、额定电压600V
-
一个电阻。用于耗散掉电容器放电时产生的热能。对于小型的电容器,电阻的最小要求为2kΩ、5W;对电源、电机启动电路和相机闪光灯电路中使用的大型电解电容器,电阻的最小要求为20kΩ、5W

thank you !!! :)
This article is by far the best I've read. I have made these in the past and had to get past the amount of words used to describe what needed to be done with what. This article is straight to the point and the tips ( using alligator clip ) are excellent.
I get the basics and can build something more to fit my needs, with what you have instructed

hi
i have one query, if it is possible to discharge the capacitor in 12V 1 A power supply..? if i cut of the power, the power supply discharge the power around 6 sec but i need to discharge it with in 1 sec ..? this is possible or Not...?
Thank you! I have been looking for a good diy discharge probe....I also used overlapping large size heat shrink to strengthen the joint at the ceramic resistor to prevent failure at a bad time.
