Question

In the finite network shown in the figure, $C_1=8\mu F$ and $C=12\mu F$. The equivalent capacitance between points P and Q is :

• A. $4\mu F$
• B. $6\mu F$
• C. $8\mu F$
• D. $12\mu F$

Answer 1

The correct option is A

$4\mu F$

$\frac{1}{C^{\prime }}=\frac{1}{12}+\frac{1}{12}+\frac{1}{12}{C}^{\prime }=4\mu FC"=C^{\prime }+C_1=12\mu F\therefore C_{eq}=4\mu F$
