Capacitor question

2024 · 5 Apr · Shift 1 · Q84

JEE MainPhysicsCapacitorNumerical+4 / −1
Three capacitors of capacitances 25μF,30μF25 \mu \mathrm{F}, 30 \mu \mathrm{F}25μF,30μF and 45μF45 \mu \mathrm{F}45μF are connected in parallel to a supply of 100 V100 \mathrm{~V}100 V. Energy stored in the above combination is E. When these capacitors are connected in series to the same supply, the stored energy is 9xE\frac{9}{x} \mathrm{E}x9​E. The value of xxx is ‾\underline{\hspace{2cm}}​.
