    1. The problem statement, all variables and given/known data
    Find the max power transferred through R in the circuit given.


    2. Relevant equations

    See attachment for the diagrams

    3. The attempt at a solution

    The Norton's equivalent resistance is 5.4Ω. For finding the Norton's current, I need to find the short-circuit current through the terminal AB.
    Applying Kirchhoff's law to the middle loop, I can write
    4(i-2)=1.43(5-i)
    i=2.79

    Thus, P = Inorton2Req = 42.04.
    But this is the incorrect answer.

    The maximum power is transferred to a load equal to the internal resistance of the generator. You calculated the power supplied to the Norton resistance, if there was no load. How much current would flow through the loading resistance R if R=Req?
