I'm using a 1 uF, 5.5V Goldcap in my circuit which will be charged with a 3,3V current, Sometimes I would like to disconnect it from whole circuit, therefore I put a SPDT switch between 3,3V Source (comes from a LM1086) and the positive of Goldcap and a LED as indicator.
the problem is once I change the switch to OFF position, the LED remains on for a while (I know, this is the normal behaviour of a Cap )
referring to this article: http://www.allaboutcircuits.com/vol_6/chpt_3/17.html, can somebody help me and say which resistor can use there to discharge the Goldcap?
Thank you.
