This will probably seem like a stupid question to those who know more about these things but why does a capacitor with bigger capacitance take longer to charge.Capacitance is a measure of how much of a charge differential it takes to create a certain voltage across its plates right. if this true then a thing with higher capacitance could store the same voltage as something with lower capacitance, but with less charge. so if i apply a voltage to two capacitors wouldn't the one with the higher capacitance "fill up" first. my logic for this:
1. a capacitor stops charging when it adopts the voltage of a source
2.This voltage is created by the charges of electrons that are stored in the plates, which can be measured in coulombs
3. a capacitor with a high capacitance will need less coulombs to create a certain voltage than one with lower capacitance
4. Then a high capacitance capacitor will stop conducting quicker than one with less capacitance because at the same rate of amperes the higher one will create the same voltage quicker
i know from experience that this isn't true, but my model for how capacitors work doesn't agree with it, could someone tell me where i'm wrong
