I have this doubt wandering through my mind for a long time.
A capacitor, according to the definition of physics, is a charge storage device. In a simple parallel plate capacitor, when electrons accumulate on one side of the plate, they push away the electrons on the other side
Let's say there are 30 electrons on either sides. If voltage is applied, 30 electrons which accumulate on one side (say plate A) must push 30 electrons on the other side (plate B). Then current flows.
But if those 30 electrons travel through the circuit and reaches the plate A, to my knowledge, the 60 electrons stay in plate A. Without any electrons in circuit (since all electrons already accumulated in plate A), how will the current flow through the circuit.
I don't know whether this question is correct. Correct me if I am wrong. Hope you understand my question.
