Homework Help: RLC Circuit Question For final exam

  1. May 29, 2016 #1
    1. The problem statement, all variables and given/known data

    (a) Write down sucient number of equations to determine all the
    currents i1, i2 and I (you do not need to solve the equations)
    (b) At the instant the battery is turned on, what is the current I
    running through the circuit?
    (c) After waiting for a suciently long time after the battery is turned
    on, what is the current I running through the circuit?
    2. Relevant equations
    i get 4 equation. You can get them down of the page

    3. The attempt at a solution
    To start, I pick 2 ways and i tried kirchhoff rule and for current i1+i2=I. dq/dt=i1 these are my prediction. İf u have a look my work upload at down, u ll understand my solution attempt.

    Hi Hap, :welcome:

    Not a very good start. What does the relevant equation stand for ?
    How about checking with your notes or textbook to find what equation describes a capacitor ? Idem inductance ?

    Did you check the PF guidelines ? 'Don't know where to start' kind of isn't good enough....

    I tried to get quick response but it didnt work so i tried somethings. Here is some works but i cant get question b and c. Maybe i can get little bit help from you guys.

    For 2nd equation: there should be mines V.
