HOW DO I KNOW WHAT VOLTAGE A CAPACITOR NEEDS TO DISCHARGE

Ask on sci.electronics.basics

Or ask the saleman - after all, "You've got questions, we've got answers (or at least dumb looks)"!

Your list does not make very good sense. General application type capacitors are rated for voltage, capacitance, and temperature. These parameters have to comply to the design needs.

Quantity @ No. of volts??

What i'm trying to do is make an eletric counter count with out me pushing a button or my help what so ever. I only have these items but i will take suggestions :

all items from Radio Shack: item No. 272-801 & 275-232

I bought the same assortment not long ago. the caps that are un rated as to voltage are probably 100 v or less

They are all ceramic type capacitors.

To make the counter count, you will need a circuit that produces pulses (or to modify the counter to produce its own 'start counting' pulses.)

Do you have a schematic of the counter? It would help.

Do you have any other test equipment like a scope and/or a logic probe?

Do you want it to count continuously and reset to zero every second? every .1 seconds? every .01 seconds?

You need to decide what it is you are trying to do before you can start to do it.
