Question

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

• A. $\frac{31}{23} \mu F$
• B. $\frac{32}{23} \mu F$
• C. $\frac{33}{23} \mu F$
• D. $\frac{34}{23} \mu F$

Answer 1

Answer: (B)

$\frac{32}{23} \mu F$

Answer 2

$\frac{8 \times 12}{18}=4 \,\mu F$
