Find the equivalent capacitance of the combination between A and B in the figure.

Explanation

Figure (a ) has been simplified as in figure (b) which is a parallel combination of `C_(1), C_(2)` and `C_(3)` . Their equivalence capacitance `C_(eq)` has been shown in figure (c )

where `C_(aq)=C_(1)+C_(2)+C_(3)`
If `C_(1)=C_(2)=C_(3)= C ` then
`C_(aq)` = 3C
