Voltage-current equation of Thevenin circuit

  1. Jan 29, 2012 #1
    1. The problem statement, all variables and given/known data

    I need help with part (b).

    2. Relevant equations

    3. The attempt at a solution

    The Thevenin resistance is 15 ohms, voltage open circuit 30 V and the short current circuit is 2 A. You can take these for granted, I've confirmed with a friend.

    I really don't know what they mean by "voltage-current equation", are they talking about Ohms law?

    Write an expression that relates the output voltage to the output current (or current vs voltage).

    Consider sticking a voltage source on the output and "measuring" the resulting current.
