Question

The figure shows a network of capacitors where the numbers indicate capacitances in micro Farad. The value of capacitance $C$ such that the equivalent capacitance between point $A$ and $B$ is to be $1\mu F$ is:

Answer 1

$\frac{\frac{32}{9}\times c}{\frac{32}{9}+c}=1$

$\frac{32}{9}c=\frac{32}{9}+c$

$C=32/23\mu F$
