Seven capacitors, each of capacitance $2\,\mu F$ are to be connected to obtain a capacitance of $10/11\,\mu F$ .Which of the following combinations is possible ?

A

$5$ in parallel $2$ in series

B

$4$ in parallel $3$ in series

C

$3$ in parallel $4$ in series

D

$2$ in parallel $5$ in series

Solution

$5(2\, \mu \mathrm{F})$ in series with $\left(\frac{2\, \mu \mathrm{F}}{2}\right), 10\, \mu \mathrm{F}$ in series with

$1\, \mu \mathrm{F}, \mathrm{C}_{\mathrm{eq}}=\frac{10 \times 1}{10+1}=\frac{10}{11}\, \mu \mathrm{F}$
