a capacitor doesn't blocks direct current until it's fully charged

loosely speaking, the capacitor doesn't block current, it behaves like a battery that opposes the real battery …

as the capacitor charges up, the opposing voltage increases; when the capacitor is fully charged, the opposing voltage equals the battery voltage, so the total circuit voltage is zero and no current flows :wink:
 


Thanks a lot tiny-tim. I got it now.
