. The equivalent capacitance between A and B is
- The above given circuit can be redrawn as shown below.
- In the above figure, all 3 capacitance are in series.
Therefore, equivalent capacitance is C'=C/3
- Now the above figure becomes,
- Both capacitance are in parallel to each other. Therefore equivalent capacitance becomes,
Ceq= C' +C= 4/3C
Hence the correct option is D, i.e. 4/3C
