The effective capacity in the following figure become points P and Q will be-

Options

A. `3mu F`
B. `5mu F`
C. `2mu F`
D. `1mu F`

Answer

D

Explanation

`(1)/(C_(1))= (1)/(3) + (1)/(3) + (1)/(3) C_(1)` is equivalent of that is series i.e., three `3muF` capacitor `rArr C_(1)=1mu F, C_(2)= 2 +1=3mu F C_(2)` is the equivalent of emf and `C_(1)` capacitor. `C_(eq)= 1mu F`
