    Hello everyone.

    I have a circuit in a asymmetric wheatstones bridge. I'm supposed to find currents through all of the branches using Millmans theorem. I am aware that Millman isn't the best solution, but thats what the professor wants.


    Any hints on how to start?

    There isn't a point which is shared by all brances so i don't know how to transform it.

    You might use Milman's theorem to solve the problem in part but you will likely need additional tools such as Thevenin's theorem and maybe the Wye-Delta [Star-Delta] transform.

    I would start by removing E5 & R5 from the circuit and use Milman's theorem for the remaining circuit. Then I would derive the Thevenin equivalent looking into the junctions where E5 & R5 were removed. Re-insert E5 & R5 to find I5.

    And so on.....

    Of course there would be many approaches - one of which is possibly the least computationally intensive.

    Read hmgjr's blog. I think he did a bridge using millman's theorem. He's the go-to person on Millman.

    Milmans theorem is also known as the parallel generator theorem.

    Use it in that form here.
