It was clearly observed that most of the voltage reduction is not purely due to the self-discharge effect but is basically due to redistribution of charge carriers deep inside pores and can therefore be retrieved from a capacitor during long-time discharging.
Resulting in the flow of current. However if you apply a DC voltage on the capacitor you will find that the charge increases from zero to max and which gives rise to exponentially decaying current. Actually charges do accumulate even around a resistor.
This is a prime reason for considering accumulation capacitors in analog circuits. There is another advantage of operating in accumulation: the capacitance is maximum and almost independent of the frequency of operation. Note that in the inversion mode, the layer charge is “isolated” by the oxide and the depletion region.
As the scan rate decreases, the longer equilibration times allow more of the electrode to be utilized for charge storage via slower equilibrating processes, such as bulk charge storage. This increase in capacitance at low scan rates is dependent on the charge storage mechanism of the system.
now if you apply alternating current on the sides of capacitor you will find that charge on one plate is constantly increasing and decreasing, which induces the opposite charge on the other plate changing with same rate. Resulting in the flow of current.
