Two capacitors, C 1 = 20 µF and C 2 =4.0 µF, are connected inparallel and charge

Question

Two capacitors, C1 = 20 µF and C2 =4.0 µF, are connected inparallel and charged with a 100 Vpower supply (b) What potential difference would be required across thesame two capacitors connected in series in order that thecombination store the same energy as in (a) if a is .12?

Explanation / Answer

Two capacitors, C1 = 20 µF and C2 =4.0 µF, are connected inparallel and charged with a 100 Vpower supply (b) What potential difference would be required across thesame two capacitors connected in series in order that thecombination store the same energy as in (a) if a is .12?

1/2*24*100*100=1/2*3.333*V*V
calculating v= 268.33V
