Combination of two identical capacitors, a resistor R and a DC voltage source of voltage \[6\text{ }V\]is used in an experiment on \[C-R\] circuit. It is found that for a parallel combination of the capacitor the time in which the voltage of the fully charged combination reduces to half its original voltage is\[10\text{ }s\]. For series combination the time (in sec) needed for reducing the voltage of the fully charged series combination by half is
