Let''s say that you want a capacitor that can supply 1 A for 1 minute while having it''s voltage drop from 10 V to 9 V over that time. That would be a 60 farad capacitor. Capacitors that large with sufficiently low series resistance are not going to come your way cheaply.
8. With an insulated-handle screwdriver, lightly touch the tip to one terminal of the capacitor. Slowly drag the screwdriver towards the other terminal, creating a short circuit and discharging the electricity stored in the capacitor. 9. Repeat this process several times, if needed, while listening for a loud pop, indicating a complete discharge.
I''m trying to find a circuit that will quickly charge a capacitor with a load(led) in the circuit but slowly discharge it (keep the led on longer than it took to turn on). Is this possible? Does ...

Now that the ohmmeter is set up, you''ll need to discharge the capacitor prior to testing. The simplest way to discharge a capacitor is to simply use a discharging resistor. This is done by connecting the capacitor to a resistor, and then allowing the charge to slowly bleed off through the resistance of the resistor until it reaches zero.
As the capacitor gets charged, the voltage accross it augments, until the battery cannot push more electrons. At this point the capacitor voltage has equalized the battery voltage. No more electrons flow, the bulb finally turns off. To release …
Step 3) To begin charging the capacitor you need either a test light or a resistor. Often times these are included with the purchase of a capacitor but can be purchased separately if necessary. A) Using a Test …
