A finite ladder is constructed by connecting several sections of $2 \mu F,4 \mu F $ capacitor combinations as shown in figure. It is terminated by a capacitor of capacitance C. What value should be chosen for C, such that the equivalent capacitance of the ladder between the points A and B becomes independent of the number of sections in between?

1 Answer

$(C)\;4 \mu F$
Hence C is the correct answer.
