To get a capacitance of \(2\, \mu \mathrm{F}\) arrangement of capacitors of capacitance \(1\, \mu \mathrm{F}\) as shown in figure \(8\) capacitors of \(1\, \mu \mathrm{F}\) in parallel with four such branches in series i.e., \(32\) such capacitors are required.

\(\frac{1}{C_{e q}}=\frac{1}{8}+\frac{1}{8}+\frac{1}{8}+\frac{1}{8} \quad \therefore C_{e q}=2\, \mu F\)
