Refer to network shown in figure. The effective capacitance between a and b is

A

C

B

`C/2`

C

`C/3`

D

`C/4`

Text Solution

Verified by Experts

The correct Answer is:
C
In figure, `C_(S_1)=C/3, C_(S_2)=C/3, C_(S_3)=C/3`
Now" "`C_(P)=C_(S_1)+C_(S_2)+C_(S_3)=C/3+C/3+C/3=C`
Now" "C and `C/2` are in series
`therefore" "C_(ab)=(CxxC/2)/(C+C/2)=C/3`
