  1. Jan 31, 2012 #1
    Hello all. It's been awhile since I took a circuits class, so any help would be greatly appreciated. Thanks in advance.
    1. The problem statement, all variables and given/known data
    See attachment for circuit drawing and question.

    2. Relevant equations

    OHM's law? V=IR
    Idiode = Io - id

    3. The attempt at a solution

    I've tried to approach this problem, but having a hard time starting it.

    Try to eliminate the bad choices.
    It's 100V, the diode is not conducting, so all the Mosfet drain current goes to the load.
