1. The problem statement, all variables and given/known data In the given DC circuit, while switches S1,S2 are open, conductor C1 is charged with Q10, and conductor C2 is not charged. After the switch S1 is closed, through conductors flows the amount of charge q1=40µC. After the switch S2 is closed, through conductors flows the amount of charge q2= -50µC. Find E3 and Q10. E5=15 V Ig=0.5 A R1=200 Ω R2=100 Ω R3=100 Ω R4=60 Ω R5=30 Ω R6=40 Ω C1=2 µF C2=5 µF 2. Relevant equations - DC circuit analysis methods 3. The attempt at a solution I tried using node voltage method, but it gives three equations with four variables. How to find voltage in the branch where capacitors are (for every case)?
