Series-Parallel RC Circuit Analysis

  1. Jul 10, 2013 #1
    I'm having a hard time understanding and solving problems in moderately complex RC circuits...
    Please Help.

    You don't have to solve right up to the numerical value, that is not my priority,

    Rather If you could just explain how to begin and process through the question, It would be best.
    Thanks. :)

    1. I'm Posting an image of the problem.



    Relevant equations and Data are given



    The attempt at a solution:
    Well, I knew, At initial stage capacitors act as wires, and at final state they behave as open switch/circuit.

    But I just don't get it how to apply that here.!

    Answers are :
    1. () 4/3 V.
    ()-10/3 V.
    ()-2V.
    () 3.3 x 10^-6 C.

    2. 4.321 x 10^-4 Joule.

    Hi FireSky! Welcome to PF! :smile:
    Both questions assume that the circuit has reached steady-state.

    (the second question specifically says so, the first doesn't but it doesn't make sense otherwise)

    To solve 1(1) 1(2) and 1(3), just use V = IR, V = Q/C, and the formulas for adding capacitors or resistors in parallel or series …

    show us what you get :smile:
