Dear Ravi

When the capacitor is charging. Current flows from the battery through the capacitor. The electrons move to one plate, but they do not jump the insulating gap inside the capacitor. They collect on the surface of the plate.

Meanwhile, electrons are removed from the other plate from the abundance that is always there in metals. That gives the plate a net positive charge. And removing the charge completes the path around which current flows.

The current is always the same on both terminals of a capacitor. You can't move charge into one terminal without removing it from the other

All the best.

when a capacitor is connected to a battery a plate is attached at high pottential end of the battery and another at low pottential end due to this pottential difference electrons get accumulated at one plate and another plate loses electrons and thus the capacitor gets charged
