Combination of Capacitors

Seven capacitors each of capacitance $2\ \mu\text{F}$ are to be connected in a configuration to obtain an effective capacitance $\left(\frac{10}{11}\right)\mu\text{F}$ . The combination is

Show answer and solution

Answer: (a)

Option (a): 5 in parallel give $10\ \mu\text{F}$ , followed by two $2\ \mu\text{F}$ in series.
$\frac{1}{C} = \frac{1}{10} + \frac{1}{2} + \frac{1}{2} = \frac{11}{10}$ .
$C = \frac{10}{11}\ \mu\text{F}$ .
So the answer is (a).
