A capacitance of $\displaystyle 2 \mu \mathrm{~F}$ is required in an electrical circuit across a potential difference of $\displaystyle 1.0$ kV. A large number of $\displaystyle 1 \mu \mathrm{~F}$ capacitors are available which can withstand a potential difference of not more than $\displaystyle 300$ V.The minimum number of capacitors required to achieve this is :
Official answer
(4)
$\displaystyle 32$
