after capacitor is fully charged
I consider when the voltage reaches the thermal noise value of the capacitor, it is fully charged. This is 20 time-constants at room temperature for any capacitor <1000μF.............................
Theoretically a capacitor connected to a voltage source through a resistor will never reach the same voltage as the voltage source.
