If the capacitance of each capacitor in the tetrahedron shown in C, then effective capacitance of the network across any two junctions is :            

A)  \[2C\]                                     

B)  C

C)  \[C/2\]                                    

D)  \[5\,C\]

Correct Answer: A

Solution :

The network can be redrawn as shown in figure   From above figure it is clear that the effective capacitance between A and B is 2C
