A finite ladder is constructed by connecting several sections of 2mF, 4mF 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 equivalent capacitance of the ladder between the point A and B becomes independent of the number of sections in between?
A
4 mF
B
2 mF
C
18 mF
D
6 mF
Answer
4 mF
Explanation
Solution
+ 2 = C, C = 4mF
