What is the effective capacitance between points X and Y?
-
- 24 µF
- 18 µF
- 12 µF
- 6 µF
Correct Option: D
Equivalent circuit 
| Here, | = | ||
| C3 | C4 |
Hence, no charge will flow through 20µF
C1 and C234 Hence, C' = 3 µF, C'' = 3 µF C' and C'' are in parallel.
Hence net capacitance = C' + C'' = 3 + 3
= 6 µF
