Question

The effective capacitance of the given network across $\text{AB}$ is

• A. $\frac{28}{9}\mu \text{F}$
• B. $4\mu \text{F}$
• C. $5\mu \text{F}$
• D. $18\mu \text{F}$

Answer 1

The correct option is C $5\mu \text{F}$

The given circuit can be redrawn as shown below

So, effective capacitance across $\text{A}$ and $\text{B}$ will be

$C_{eq}=2+3=5\mu \text{F}$

Hence, option $\left(c\right)$ is correct.
