    hi, im new to the forum so im not sure this is the right category.

    any way.

    i have this circuit consisting of parallel and series resistors.

    the problem for me is that i cannot figure out how to add up all the resistors

    [​IMG]

    if you guys could help me to make rth, i think i should be able to do the rest.
    MY RLOAD IS R4

    thanks

    Without a sketch of your circuit, we are powerless to assist you with your question.

    When you say that R4 is the load, do you mean that you need to remove R4 and then calculate the Thevenin equivalent of all the rest?

    Replace both voltage sources (V1 & V2) with nothing by removing them and then:
    Add up R6,R2,R3 in parallel. Add the parallel combination of (R6,R2 & R3) with R1 and R7 in series

    Good Luck

    You can solve this by using the superposition theorem too but that would be longer..
