# Prove the following

Question:

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