Given that CA = 1µFCB = 2µF, and CC = 2µF, Initially each capacitor was charged to potential differences of VA = 10VVB = 40V and VC = 60V separately and are kept as shown in figure (a). Now they are connected as shown in figure(b). The positive and negative sign shown in figure (b) represent initial polarities. If total amount of heat produced in µJ is given by (3100 – N) by the time steady state is reached find value of N.
    Correct answer is '75'. Can you explain this answer?

    q1 – q3 = 10 – 120 = – 110    ...(1)
     –q2 + q3 = – 80 + 120 = + 40    ...(2)
    In the final state


    Solving we get q3 = 65μC
    The charge on lower plate of capacitor CC changes from  –120µC to –65µC
    Hence the charge flowing through shown connecting wire is
    (120 – 65) = 55 µC
    final charges  
    q3 = 65µC ; q2 = 25µC ; q1 = 45µC
    Heat produced = Ui – Uf  

    = 3025 µJ
    The correct answer is: 75
