    Ok I think I have figured this series-parallel circuit out correctly. Could someone please reveiw the attachment and let me know if I am doing this correctly.

    Thank you

    AlV.

    You made an error at R5, in the table and carried forth that error causing other problems in your subsequent calculations.

    Other than that, I think your getting the flow of things. Revisit your process on doing those calculations.

    I concur with joejester's assessment across the board.

    A little revisiting and I think you will have it. Good work so far.

    OK, what did I do wrong. The way understand it is: since Rw and R4 are in series would they have the same current (.3A) flowing through each other. So I'm pretty sure that V2/I2 and V3/I3 are correct.
    So my mistake at R5 should be V5 18 volts vice 12 v that I originally wrote. Then the current at I5 is .3A and that the total current in the circuit would be .6 A Which would then mean that Et would be 72 v.

    Is this now correct or am I still not understanding this material.

    You are correct in that assumption.

    You corrected the error, at R5, and now your Et and Rt are correct.

    I believe you are understanding the material.

    Good job.

    Thank you for the assistance. I think that I'm starting to understand these series-parrallel circuits.
