Question
Effective capacitance between points 
in the figure, shown is
The correct answer is:
The points 
will be at same potentials since,
Therefore, capacitance of 2
will be unaffected.
So, the equivalent circuit can be shown as.
The effective capacitance in upper arm in series, is given by
The effective capacitance in lower arm in series is given by
Hence, the resultant capacitance in parallel is given by
