Homework Help: Find the equivelent resistor

  1. Feb 21, 2014 #1
    1. The problem statement, all variables and given/known data
    R1 = 1K Ohm
    R2= 50K Ohm
    gM = 100mA/V

    I should find the equivelent resistor seen from the two terminals on the left

    2. Relevant equations

    Nodes equations, Ohm's law.

    3. The attempt at a solution

    So, I started by putting a test voltage source on the left but I end up with 2 variables on the equivalent resistor equation that I can't be able to solve.
    I did Circuit analysis last year, which I passed but now I'm a bit rusty with this. Anyone can help me?
