D

3C

Text Solution

Verified by Experts

The correct Answer is:
B
The form a wheatstone's network
`therefore`Arm QS is ineffective
`because C' and C` are in series in PQR their resultant is `(C)/(2)` similarly in the branch PSR. Resultant is `C/2` and `C/2 and C/2` are in parallel
`therefore `resultant capacity is C.
