15 identicle capacitances each of 1uf are conected in a hexagonal network ABCDEF such taht each vertex is connected with each of the others directly by 1uf cap...the cap and wires r insulated from each oder(imagine ech of the lines joining the vertices including the sides has a cap which is ommitd for clarity

find the eff CAPACITANCE BETWEEN VERTEX A AND D

here, CF is the line of symmetry for the circuit ! hence all points on the the lines perpendicular to CF are at same potential.......this will help..go ahead ! [1]

taking forward de arguement by debotosh,

keep in mind that the points B, F and C, E are symmetric wrt to A and D

so remove those lines..

Then since B, F are at the same potential reflect everything about the line AD to get each capacitor replaced by 2 capacitors in parallel.. (except on the line AD!)

THen calculate the capacitance.
