Hi I'm wondering why does the charge resides on the plates on a capacitor when it's charged but not on say two closely placed wires or circuit traces etc, well I do understand that charges stay on capacitor plates because the opposite charges tend to attract and with a distance between them they stay as close as possible for as long as possible. So the question is more like , given the same amount of voltage does the charge accumulation depends on the conductor geometry or spacing between them ? Say I have a parallel plate capacitor and two wires with the surface area the same as that of the plates , and the gap between each of the wires just as big as that of the plates will they ahve the same capacitance or no? P.S. although I think it's impossible but would it be possible to make a capacitor which looses it's charge right after the source or the supply is taken away , well it wouldn't be a capacitor anymore but still , say I needed a device with which I can use + charge to attract some negative charge on the other plate but let it go just as when I disconnect the positive charge ? As upon disconnecting a capacitor it would discharge slowly.
