Question

Find net capacitance between A & B

• A. $6\mu F$
• B. $7\mu F$
• C. $\frac{8}{3}\mu F$
• D. $\frac{9}{4}\mu F$

Answer 1

The correct option is A $6\mu F$


The given circuit can be reduced to the above form. Since this wheatstone bridge is balanced, no current flows through the $5\mu F$ capacitor.

$\left[6\right(s\left)12\right]\left(p\right)\left[3\right(s\left)6\right]$
$\Rightarrow 4\left(p\right)2=6\mu F$
Here $p$ stands for parallel and $s$ stands for series.
