Q.
A finite ladder is constructed by connecting several sections, of $2\mu F,4\mu F$ capacitor combinations as shown in the 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
A) $4\mu F$
B) $2\mu F$
C) $18\mu F$
D) $6\mu F$
Explanation
(a) If the value of $C$ is chosen as $4\mu F,$ the equivalent capacity across every part of the section will be $4\mu F$
