Two electric bulbs are connected one by ...

Two electric bulbs are connected one by one across potential difference V At that time power consumed in them are `P_1` and `P_2` respectively. Now, if potential difference V is applied across series combination of these bulbs, what will be total power consumed ?

A

`P_1 +P_2`

B

`sqrt(P_1 P_2)`

C

`(P_1 P_2)/(P_1 +P_2)`

D

` P_1 P_2`
