Homework Help: Thevenin's equivalent circuit problem

  1. Nov 5, 2008 #1
    1. The problem statement, all variables and given/known data
    use thevenin's theorem to find the current in the 3 ohm, parallel branch, resistor

    2. Relevant equations
    Thevenin equivalent circuit, voltage divider rule


    3. The attempt at a solution

    I dont think its possible, since thevenin's theorem ends up with a voltage source and a resistor in series, you can only find currents and voltages in components that are in series. In this circuit there is nowhere to make the cut and split the circuit across terminals A and B. Normally you'd need Norton's equivalent circuit to find the current in the 3ohm resistor. Am I right, or is there actually a solution using thevenin's?
