Hi, i had some general questions about capacitors. First of all, when a capacitor charges up, do actual charges travel through the plates? like does it charge up to a threshold (the capacitance value) and then the charges travel from one plate to the other through the air/dielectric? Also, whether arranged in series or parallel, i understand that voltage varies with the connection. But im confused as to whether the charges remain the same in both connections. for example, if you had a 2 capacitors of different values, arranged them in series, would they contain the same charge in each capacitor as they would if they were arranged in parallel?
