Finding the current and the voltage across each resistor

  1. May 11, 2013 #1
    1. The problem statement, all variables and given/known data
    Find the current and the voltage across each resistor.

    volts is 24v
    R1=270 ohms
    R2=330 ohms
    R2=1.2k ohms
    R4=1.2k ohms


    2. Relevant equations



    3. The attempt at a solution
    This is not a hw its more like a study guide.
    He gave us the answer for just the currents which are
    IR1=20
    IR2=20
    IR3=10
    IR4=10
    But not sure how he got that.
    this is what i did but don't know how to go from there:
    (270+330)|| (1.2k||1.2k)
    600||600
    R=300

    Hi Lopez. Welcome to physics forums!!!

    The 270 and 330 are in series with the 600, not parallel.

    Having reduced the (1.2k||1.2k) to an effective 0.6k, what is the relationship of that in the circuit to R1 and R2?

    ahh yes there was the problem,after 1.2 k and the other 1.2k were combined it becomes one resistor in series with the (r1 and R2). Thanks!
