This explains why during the initial phase of charging a capacitor the current (rate of charge delivery) is maximum. However as net charge builds up, the attraction and repulsion forces increase resisting the transfer of additional charge. So now the current (rate of charge delivery) is decreasing as the voltage across the capacitor builds.
