Figure shows a network of capacitors where the number indicates capacitances in micro Farad. The value of capacitance C if the equivalent capacitance between point A and B is to be $1 μ F$ is :

Options:

Answer:

Solution:

$All capacitances below are in μ F . C_{L} = \frac{8 ( 2 + 2 )}{8 + 2 + 2} = \frac{8}{3} C_{6, 12} = \frac{6 \times 12}{6 + 12} = 4 C_{R} = \frac{1 ( 4 + 4 )}{1 + 4 + 4} = \frac{8}{9} C_{N} = C_{L} + C_{R} = \frac{32}{9} \frac{1}{1} = \frac{1}{C} + \frac{9}{32} C = \frac{32}{23} μ F (A)$
