In the image above, gray dots are capacitors of capacitance .
That gray area shows that, there is infinite arrangement of capacitors, such that first circle has 4 capacitors , second one has 8 capacitors, third 16 capacitors and next 32 and so on, as shown.
Find the equivalent capacitance in between the two terminals (at the center) and (at infinity).
