Two capacitors, C1 = 20 µF and C2 = 5.0 µF, are connected in parallel and charged with a 150 V power supply A.) Energy Stored I found to be is 2.81*10^-1 J B.)What potential difference would be required across the same two capacitors connected in series in order that the combination store the same energy as in (a)? Delta V= sqrt of (2*Energy stored/C) This eqn can b used to solve for delta V I have no idea what im doing wrong! I have used the capcitor in parallel combo of C= C1+C2..... Then I have converted the microFaraday charges of these sums to Faraday but no success Any Suggestions??
