Homework Statement
Two capacitors of capacitances 3μf and 6μf are charged to potentials of 2V and 5V respectively. These 2 charged capacitors are now connected in series.Find the charge and potential difference across each of the capacitors now.
Homework Equations
The Attempt at a Solution
Q1=C1V1 Q2=C2V2
Q1= 6*10-6 Q2=3*10-5
Total charge Q= 36*10-6C
Net capacitance of combination in series.
1/Cs= 1/C1 + 1/C2
Cs= 2μf
Potentital difference of system in series = Q/Cs
V= 18V
The problem I am facing is finding the charge on each capacitor. I don't think it can be the same as before because the potential differences across them definitely would have changed. And in rule, capacitors in series get the same charge. So does that mean the 36*10-6C splits equally between them? Or do they both have 36*10-6.C And for either, why?
