Question:
It is required to construct a $10 \mu \mathrm{F}$ capacitor which can be connected across a $200 \mathrm{~V}$ battery. Capacitors of capacitance $10 \mu \mathrm{F}$ are available but they can withstand only $50 \mathrm{~V}$. Design a combination which can yield the desired result.
Solution:
