If capacitors charge and discharge at same rate why use one?
How fast you can charge and discharge a capacitor is ultimately decided by the internal resistance of the capacitor. There isn''t really a similar limit to how slowly you can discharge it, but ultimately you''ll get to a point where the self-discharge is significant. Say a given capacitor has a self-discharge time from full to empty of 12 hours.

The resistance determines how fast the charge will transfer from one capacitor to the the othr. The final state is determined by the equality of the potential diference across the two capacitors. The final voltages and charges are not dependenton the value of the resistance. No charge is lost in the resistor.
