Homework Help: Quick question about finding Thevenin equivalents

  1. Aug 22, 2009 #1
    1. The problem statement, all variables and given/known data
    When finding the Thevenin resistance for a circuit, there is a method involving applying either a test voltage source or a test current source at the terminals a and b. My teacher didn't really go into this in very much detail so I was wondering if you can specify any value for the test sources? i.e. I can place an arbitrary voltage source (say 5 V) at the terminals, find the current I_t through the source and have R_Th = 5/I_t?


    2. Relevant equations

    3. The attempt at a solution
