I was going through charging of capacitor .I did not understand one thing .Plates of capacitors are uncharged initially but when battery is connected to it ,(positive terminal of the battery is connected to the Plate 1 and negative terminal of the battery is connected to plate 2)electrons from one of the plates (plate 1)start coming out from there to the positive terminal of the battery and as a result that plate (plate 1) of the capacitor becomes positively charged .This continues up to the time when potential of plate 1 becomes equal to the potential of the positive terminal of the battery .Similarly from the time we connect battery to the plate2 elcectrons from the negative terminal start going to the plate 2 in order to be as close as possible to plate 1 as it has positive charge which attract electrons.
Electrons of plate 1 stop because the potential of plate 1 equals potential of the positive terminal .Why electrons of negaitive terminal stop?
But the thing I don't understand is why electrons stop (going from negative terminal of the battery )at the same time when electrons from plate 1 stop going towards positive potential of the battery?Why ?
