    1. The problem statement, all variables and given/known data

    I want to see if I'm reducing the following circuit correctly.

    2. Relevant equations



    3. The attempt at a solution

    The two outer resistors are in series:

    ##R_{56} = R_5 + R_6##

    Now the outer resistors would be directly wired on each end after simplifying. Hence:

    ##R_{456} = (\frac{1}{R_4} + \frac{1}{R_{56}})^{-1}##

    Series again:

    ##R_{2456} = R_2 + R_{456}##

    Parallel:

    ##R_{32456} = (\frac{1}{R_3} + \frac{1}{R_{2456}})^{-1}##

    Series:

    ##R_{132456} = R_1 + R_{32456}##

    Now if we had the emf we could find the current and work backwards if needed.

    Looks reasonable. Looking for the current i6 there may be easier ways though. They should all amount to the same in the end.
