What happens to current flow in a capacitive circuit when the DC voltage across the capacitor is

What happens to current flow in a capacitive circuit when the DC voltage across the capacitor is approximately equal to the source voltage?

Last answer: Capacitor always charges up to the voltage of source. When the capacitor is charged to same as source voltage then there is no current flowing through the capacitor. The current through the capacitor is called displacement current.
