Combination fo two identical capacitors,...

Combination fo two identical capacitors, a resistor `R` and a dc voltage source of voltage `6V` is used in an experiment on a `(C-R)` circuit. It is found that for a parallel combination of the capacitor the time in which the voltage of the fully charged combinatiomn reduces to half its original voltage is `10` second. For series combination the time needed for reducing teh voltage of the fully charged series combination by half is-

A

`10` second

B

`5` second

C

`2.5` second
