When the capacitor is fully charged

capacitor fully charged, a long time after the switch is closed. When the capacitor has been allowed to charge a long time, it will become "full," meaning that the potential difference created by the accrued charge balances the applied potential. In this case, the first and third terms of the Kirchhoff loop equation for the outer loop cancel ...
