Question

The equivalent capacitance between point $a$ and $b$ in the combination of capacity figure is

• A. $15\mu F$
• B. $10\mu F$
• C. $11.2\mu F$
• D. $7.4\mu F$

Answer 1

The correct option is C $11.2\mu F$

FOR IMAGE 01: The series combination are:

$[C_s=\frac{2\times 3}{2+3}=\frac{6}{5}\mu F]$

FOR IMAGE 02: The parallel Combination are:

$C_{eq}=4+\frac{6}{5}+5$

$=\frac{56}{5}=11.2\mu F$
