Well what I read that in the process of charging a Capacitor, charges are transferred from one plate to another. The work done to move a charge from one plate to another stores as electrical potential energy in it and the capacitor is charged up.
Before this I read that when a Capacitor is placed in a circuit with switch closed, positive charges pile up at one end/plate of the capacitor inducing same amount of negative charges on the other end of the capacitor. This continues till the voltage across the capacitor becomes equal to the voltage of battery. This way a capacitor is charged up.
In both of these what I found that there is only induction of charges at another plate due to charge present at the 1st plate. There is no transference of charges between the plates of capacitor while charging up the capacitor.
Why this is so?
I know I am wrong somewhere but where I don't know. Please tell me an appropriate answer for this doubt. Thanx

There are no charges traversing between the plates because between the plates there is a strong insulating dielectric material. Charges on both plates are supplied by the battery. Through the electric field that crosses the dielectric they feel the presence of the charges on the other plate.
