Question

Version CC 7. You want to connect a 12 F capacitor and a 6 F capacitor to a constant potential source. How should you connect them so that when the capacitors are charged, the 6 F capacitor will have a greater amount of stored energy than the 12 F capacitor? The two capacitors should be in parallel This is impossible no matter how the capacitors are connected The two capacitors should be in series The two capacitors can be either in series or parallel-in either case the 6 F capacitor has more stored energy A. C. D.

Explanation / Answer

C. the two capacitors should be in series.

in series both have same charge (Q).

energy stored = Q2/2C

since Q is same for both the capacitors, energy stored is inversely proportional to the capacitance.

so, 6uF capcaitor will hve more energy stored thn the 12uF in this case
