I am very new to electronics, and I am trying to use a capacitor to make my LED's stay on a little longer after I turn it off. I know that the voltage on the capacitor is the maximum limit of voltage it can take, and the fared unit of the capacitor is the capacitance, but that wasn't really clear to me, so I made a list of some stuff that I need to know to complete my goal.
Does a higher capacitance affect the time the charge is held?
If I had 5 100uf capacitors, and I connected them in parallel (which will give me 500uf), will it perform the same way as a 500uf capacitor (that was not combined with others)?
Does different types of capacitors hold charges longer than others?
Thank you all for feedback, help, and tips :)
