Find the equivalent capacitance of the infinite ladder shown in figure (31-E17) between the points. A and B.
Let the equivalent capacitance be C, since it is an infinite series, So, there will be negligible change if the arrangement is done as in Figure.
⇒ (2+C) C=3 C+2
⇒ (C−2) (C+1)=0
⇒ C=−1 (impossible),
So, C=2 MF
