sallehuddin,
U just, connect a resistor parallel to the charged
capacitor, some low value will be fine
It needn't even be a low value. The reason for not just discharging it by
shorting the leads is that short circuit current can damage the capacitor,
not usually an amount that you will notice but a little. This might be more
true of 'lytics. It's a bit like the static on cmos, probably won't kill it
but might shorten it's life.
