Electric Capacitance, Energy of an Electric Field

Problem 3.114

A capacitor of capacitance \(C_{1}=1.0 \mu \mathrm{F}\) withstands the maximum voltage \(V_{1}=6.0 \mathrm{kV}\) while a capacitor of capacitance \(C_{2}=2.0 \mu \mathrm{F},\) the maximum voltage \(V_{2}=4.0 \mathrm{kV} .\) What voltage will the system of these two capacitors withstand if they are connected in series?

Reveal Answer
V⩽V1(1+C1/C2)=9kVV \leqslant V_{1}\left(1+C_{1} / C_{2}\right)=9 \mathrm{kV}
